The funny thing is, we do this shit a lot and we're in 11th year top set math. I think our teacher is trying to fuck with us or something.
[QUOTE=ProgramFiles;20476939]Wow, you're 11 or something, this stuff is old for me.
Man i regret that message, such a weak 2.500th post.[/QUOTE]
I'm actually in Liberal Arts (Between Geometry and Algebra 2) We do Algebra 2 content at a shit slow pace.
what?, I could do this, and I'm in algebra 1
Can anybody show me how to factor? =)
Hmm, what do you want to factorise?
I learned off some chick on facebook.
Oh, okay :v:
-3(x - 9) + x(x - 9)
You take (x - 9) out as the common factor (It's a straightforward translation from mah language).
You get (x - 9)(-3*1 + x*1) = (x - 9)(x - 3)

are u leik rtarded or smth =?

I always factored by grouping. But I still have problems sometimes with factoring.
[QUOTE=Epic Sandwich;20475065]For solving equations in the form of ax^2 + bx + c = 0 and if you have a calculator, you can use these equations. They'll give you both answers if you can't be bothered working it out yourself:
(-b+sqrt(B^2 + 4ac))/2a
(-b-sqrt(B^2 + 4ac))/2a
They look stupid on here but they're actually quite simple.[/QUOTE]
What no
The determinant is -b^2[B]-[/B]4ac (notice the minus)
[QUOTE=i_speel_good;20477659]What no
The [b]determinant [/b]is -b^2[B]-[/B]4ac (notice the minus)[/QUOTE]
You mean the discriminant :eng101:
and it's b^2-4ac
Sorry my bad, thought it looked a bit strange.
Can i ask how old you are? We were doing this stuff age 14.
The fuck, I do this when I was in algebra 1...
Lucky bastard :(
I graduated high school and I don't even know how to do that.

You have substandard intelligence. Sorry.
[QUOTE=Encryption;20473618]Write each polynomial as the product of two binomials.
I need somebody to explain to me how to do this, step by step, not just do it for me.
-3(x - 9) + x(x - 9)
Online help is currently offline -_-[/QUOTE]
This is Algebra 2? I remember doing distributive property in 8th grade.
Um...
Notice how there are two (x - 9)? Just take their coefficients and "undistribute" them:
(-3 + x)(x - 9) or (x - 3)(x - 9)

algerbra 2 is just a review for the first two months
Shit, that's Algebra 2? Fuck man that's low-level algebra.

Hahah, you still think educated is the same thing as intelligent.
[QUOTE=Jund;20476899]Or maybe [i]your[/i] teachers are really dumb, I learned pre-algebra at the end of 6th grade.[/QUOTE]
uhhh you do know that it goes from general math > pre-algebra > algebra 1 > geometry > algebra 2???
which means he's saying he started pre-algebra in 3rd grade.
I never took pre-algebra in the first place
skipped it
