Question

Change the fraction w − 3 / w + 5 into an equivalent fraction with the denominator w2 + w – 20.

Answer 1

i think it is \[\left(\begin{matrix}w^2 + 7w + 12 \over w^2 + w - 20\end{matrix}\right)\]

Answer 2

the numerator should be w^2 - 7w + 12
because you are multiplying (w - 3) by (w - 4).

Answer 3

thank you
