Hi. if there are any people good at

"Factorizing Quadratic Trinomials"

Factorise these expressions

1. x(Squared) + 6x + 8

2. x(Squared) + 5x + 4

3. x(Squared) - 4x - 5

4. x(Squared) - x - 20

5. x(Squared) + 8x - 20

6. x(Squared) - 8x + 15

7. x(Squared) - 17x - 60

8. x(Squared) - 15x + 56

9. x(Squared) - 20x + 100

10. x(Squared) + 18x - 40

iF ANYONE GIVES ME ANSWERES TO THESE I WILL BE SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO GRATEFUL!

Don't cheat! That's a pathetic and IMO disgraceful thing to do by coming to these boards and cheating. Being absent a lot is not an excuse to cheat on your work Laraluva, tutorials, after school work, extra credit, all these can help you know.

For those who are helping, I know you mean to help but giving off answers like that is not helping. Maybe an online tutoring or something but shooting off answers is no way to help Laraluva.

I know most of you don't care what I typing down and that's okay, you don't need to listen to one if you don't want to, I'm just saying what's right and true. Cheating gets you nowhere. What if your teacher was a member of these forums Laraluva and saw his/her work being answered like that? http://www.tombraiderforums.com/images/smilies/whistle.gif

I guess you can keep cheating if you want but just remember every CAUSE has an EFFECT.

Catapharact
05-08-05, 01:18
I agree. Well for one thing Camera Obscura, I don't think LaraLuva4Eva has intetions of cheating since he/she has only asked for the answers. In Math, you usually get full marks if you have the procedure down as well. LaraLuva4Eva, use the answers as a reference, but I do want you to try these on your own http://www.tombraiderforums.com/images/smilies/smile.gif . If you need further help, I'll try to be on as long as possible.

LOL! Thorn. Machies don't enjoy laughing so much :D LOL!!!

Im sorry Camera, but im not interested in ANYONE's opinion, i only needed some help. those questions were approx 1/16th of what i had to do, so when I asked for answers, i didnt even ask for half the worksheet! :(

Why are you doing this? it ISNT cheating, if anyone doesnt agree with me, you are an idiot,

This is just my opinion. ;)

Thanx anyway Cata!

Oh no! Not Quadratic Trinomials!
I only did these last year, and i'm already confused! Has it been that long a summer?!

Aww come on! Quadratics are FUN!

LaraLuva4eva, how old are you if you dont mind me asking?

Catapharact
05-08-05, 15:30
In agreement with Andromeda66 LOL! These are just the simple Quadratics. Wait till you come across the dreaded Quadratic Formula or derivitives for that matter LOL!

It's easy, but a pain to memorize LOL!

Damn, this makes me wish I remembered my math. It's really sad, I just graduated in the summer of 2004 and I've already forgotten a lot!!! I even took entry-level university calculus... I think if I were to do it all again it would come back to me easily enough.

I think I used to be good at algebra... but I have lost my touch. Algebra is easy in physics because it's just simple rearrangements of formulas... this stuff I can't remember, and it bothers me a LOT.

I mean, what's the purpose of taking all the highest level courses in school when you just forget a lot of it anyway? The only courses from which I still easily remember the skills I learned are English and Social Studies. In my opinion, you either grasp that right away or you don't (from what I've seen, for the most part). Math and sciences are different because you memorize processes and theories.

Those are skills I've had since forever (one of those 'natural talents' I guess), so I take them for granted. I'm more interested in math and science and that consists of the bulk of what I've forgotten!!! :(

Math for the most part is simple practice http://www.tombraiderforums.com/images/smilies/smile.gif . Once you just get down right into it and redo the problems with different senerios again and again, you teach your brain to analyze the questions and solve them http://www.tombraiderforums.com/images/smilies/smile.gif .

Practice makes perfect :D LOL!

It's easy, but a pain to memorize LOL! The formulas for integrals are really a pain to memorize. But still fun, once you know them off by heart.

In school I was like that too, MissNATLA. I'd be up until 2 or 3 am doing schoolwork, wake up at 6 in the morning, go to school at 8, be home by 3:30... and do it all over again. I think I averaged about 3-5 hours of sleep per night.

Oddly enough, I was never tired or falling asleep in class (during my last year of high school, at the very least), and when I got more sleep than usual, THAT was when I felt my most tired.

I also never missed a single day (with an exception to the snow day which was excused automatically because only 3 people from my grade showed up).

It was nuts... probably why I seemed a tad kooky to other students.

But there's a difference between help and cheat. I just wanted to make that difference clear Laraluva.

Hey since you're in Australia I'm not sure how helpful this will be to you, but you might find it useful to check out the BBC Bitesize website for maths stuff, it's got everything in the British maths courses there so if quadratic trinomials aren't your hot point you might pick up some tips there that your teacher didn't give you that'll help make things click better. I know it's helping me a lot. http://www.tombraiderforums.com/images/smilies/smile.gif

aargh!! I never learned that in high school because we didn't actually have math at my school. We had this program called Core Plus. My class was the first class to have to start taking it and almost every single person in my class bombed the math section of the ACTs because of it. I am not kidding you. My high school does not have geometry, algebra, trig, or any of that. We have Core Plus, and then calculus.
Anyone else cursed with the wretched Core Plus program?

o.O Omg you're so lucky yours_in_darkness. http://www.tombraiderforums.com/images/smilies/vlol.gif XD I'm okay at maths, but I find algebra quite hard....quadratic equations... :eek: Lol
Laraluva4eva I think what camera obscura means is that it might be of more help to ask for the method of finding the answers to the questions rather than just asking for the answers. I don't wanna get into a huge debate here but that's my opinion anyway at least. Argh...prelims coming up in November... :( Hey, my friends use the word Trinomial to freak me out! :mad: Meh...

If you're asking for the answers on here and someone gives you them, it's a short term fix because for now your teacher will think you can do them.

But, you're so screwed when it comes to the exams.. and that's when it counts.

Andromeda66
06-08-05, 15:13
I agree with you. LauraKR17

Anyways, I dont find math so bad. Its fun, even at university level. I just feel it doesnt serve to well as a life-long profession.

But, you're so screwed when it comes to the exams.. and that's when it counts. That's exactly my point. For those who (On a regular bases) cheat, that would be the outcome of it. And for those who do it RARELY, it's still cheating either way.

And Laraluva4eva, I'm not out to get you or anything and I'm definitely not trying to force you to stop, all I'm doing is trying to get a point through.

Catapharact
06-08-05, 18:52
Giving just the answers doesn't count as cheating. The person still has to do the procedure of the problem in question to recieve the full marks. Just the answers aid a person to understand and direct themselves towards the procedure.

To LaraLuva4Eva:

Good to know that you understand them now http://www.tombraiderforums.com/images/smilies/smile.gif . Glad to be of help http://www.tombraiderforums.com/images/smilies/smile.gif .
