Question

I still need help with this one. Am I correct?
9r^3s-16rs / 4s^2-3rs

rs(9r^2-16) / s(4s-3r)
rs(3r+4)(3r-4) / s(4s-3r)
r(3r+4)(3r-4) / 4s-3r

Answer 1

We have to factor first then cross out. I got r(3r+4)(3r-4) / 4s-3r. I just don't know if that is correct.

Answer 2

Looks good to me.

Answer 3

\[ \large
\frac{r(3r-4)(3r+4)}{4s-3r}
\]

Answer 4

Thank you!
