simplify your numerator first

OpenStudy (anonymous):

I put two of them together, the bottom was same so i only put one

OpenStudy (anonymous):

(x-9)(x+2)

OpenStudy (lgbasallote):

wait...your numerator was originally (x-9)(x+2)????

OpenStudy (anonymous):

thats the bottom right?

OpenStudy (anonymous):

OpenStudy (lgbasallote):

oh...that's 4x - 5 - (3x-7)/x^2 - 7x - 18 when combined

OpenStudy (anonymous):

:) so whats next? I keep getting x-12 over the denominator :/ which i know isnt right

OpenStudy (lgbasallote):

actually it's x+2/denom

OpenStudy (lgbasallote):

and obviously something is cancelable (made that word up)

OpenStudy (anonymous):
