**Sabrina**, Friday, September 24, 2010 at 5:58pmI cannot figure this out! I know that the top is essentially the same as the bottom. SO what do I do?

(r^2-64)/(r+8)^2=

(r^2-64)/(r^2+64)=

0 ?

**Reiny**, Friday, September 24, 2010 at 6:13pmnot correct

do it this way ...

(r^2-64)/(r+8)^2

= (r+8)(r-8)/[(r+8)(r+8)]

= (r-8)/(r+8)
