Multiply. Simplify the product.
-2n 7n+7
------- x -----------
7(n+2) n+1
I'm having trouble typing the fraction so, i'll say it in words.
-2n over 7(n+2) times 72+7 over n+1
Thanks in advance!

Hello, alicec4ever!
We are supposed to factor and reduce . . . then multiply.
Multiply: .$\displaystyle \frac{-2n}{7(n+2)} \cdot \frac{7n+7}{n+1}$
Factor: .$\displaystyle \frac{-2n}{7(n+2)}\cdot\frac{7(n+1)}{n+1} $
Reduce: .$\displaystyle \frac{-2n}{{\color{red}\rlap{/}}7(n+2)}\cdot\frac{{\color{red}\rlap{/}}7{\color{blue}\rlap{//////}}(n+1)}{{\color{blue}\rlap{/////}}n+1} $
and we have: .$\displaystyle \frac{-2n}{n+2} $
