factor
OpenStudy (anonymous):
idk how
OpenStudy (luigi0210):
Well we are screwed now aren't we? :P
OpenStudy (anonymous):
Ok this is what i got:
2a^2-4a+2/3a^2-3=2(a-1)/3(a+1)=\[a \neq-1\]
OpenStudy (anonymous):
But my teacher said I need to show my work so now what? @Hero

lol
OpenStudy (anikhalder):
the second a^2 in 2/3a^2 is in the denominator?
OpenStudy (jhannybean):
\[\large \frac{2a^2-4a+2}{3a^2-3}\] first step, let's start with the numerator.
divide the numerator by 2. what do you get?
OpenStudy (luigi0210):
wait for it...
OpenStudy (jhannybean):
second step, divide denominator by 3, what do you get?

Um idk 3a^2?
OpenStudy (luigi0210):
\[\frac{ 2(a^2-2a+1) }{ 3(a^2-1) }\]
OpenStudy (jhannybean):
lol not factor OUT, divide!!!
OpenStudy (luigi0210):
I'm not sure if you can divide..
OpenStudy (luigi0210):
but then again you're the expert

OpenStudy (jhannybean):
numerator : (2a^2)/2 - (4a)/2 + ( 2 )/2
denominator (3a^2)/3 - (3)/3
OpenStudy (jhannybean):
can you simplify these? lol. That's what i meant.
OpenStudy (anonymous):
ok
2(a-1)/3(a+1)?
OpenStudy (luigi0210):
see you can factor, good job
OpenStudy (luigi0210):
