I have \(6x^4-18x^3+12x^2\)... it's just been a long time since I've done this xp
Nnesha (nnesha):
haha it's okay
so first you have to find GCF(greatest common factor ) then you will get a QUADRATIC equation
OpenStudy (bloomlocke367):
6x^2, right?
Nnesha (nnesha):
it's a quadratic equation.
Nnesha (nnesha):
yep right!

and I pull that out first, right? I think I'm remembering now XD
Nnesha (nnesha):
yes take out the common factor :)
OpenStudy (bloomlocke367):
so I have \(6x^2(x^2-3+2)\)
OpenStudy (bloomlocke367):
-3x****
Nnesha (nnesha):
yep right

sooooooo i have \(6x^2(x-1)(x-2)\)
Nnesha (nnesha):
perfect!
OpenStudy (bloomlocke367):
is that it?...
Nnesha (nnesha):
i didn't foil it to check ur answer
-1 times -2 =+2 perfect
-1-2=-3 which is middle term perfect! so that's right
Nnesha (nnesha):
