first, you want to flip the second fraction, so the bottom is on top, and the top is on bottom. Understand?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
so once you have those flipped, you want to cancel out any variables that are the same on both bottom and top. Do you see any?
OpenStudy (anonymous):
ok 2x^4

do you mean 2x^2?
OpenStudy (anonymous):
yeah sorry
OpenStudy (anonymous):
alright so once you cancel those out, you are left with \[9x +9/-5x-12 \times -4x ^{2}-4x+80\]
OpenStudy (anonymous):
oops. I wrote that wrong
OpenStudy (anonymous):
ok

(9x+9/-5x-12) x (-4x^2-4x+80/x^2+8x+15)
I hope you have paper you're doing this on.
The next thing you need to do is see if you can simplify anything. Can you?
OpenStudy (anonymous):
no
OpenStudy (anonymous):
well what about the second part of this equation. you can use the quadratic formula to simplify both the bottom and top. Do you know the quadratic formula?
OpenStudy (anonymous):
yes i do let me use that
OpenStudy (anonymous):
Tell me when you have it
