First you need to expand the equation on the right side
OpenStudy (anonymous):
okay so,
7(1-x)=(3x+2)(x-1)
OpenStudy (anonymous):
No right side (3x+2)(x-1)
OpenStudy (anonymous):
whoop
7-7x=3x^2-x-2

Sorry keep getting cut off...Now subtract 7 from both sides.
OpenStudy (anonymous):
-7x=3x^2-x-9?

@nelsonjedi
OpenStudy (anonymous):
Now add 7x to both sides

We are tring to get a quadratic equation that we can solve.
OpenStudy (anonymous):
oh I see, so you're then left with
3x^2+6x-9
(3x-3)(x+3)
{1,-3}?

OpenStudy (anonymous):
