5-11.

Simplify.

1. $\frac { ( x + 2 ) ^ { 3 } } { ( x + 2 ) }$

Rewrite the numerator as $\left(x + 2\right)\left(x + 2\right)\left(x + 2\right)$.

1. $\frac { x ^ { 2 } - 5 x + 6 } { ( x - 2 ) ^ { 2 } }$

Factor and simplify.

1. $\frac { 2 x ^ { 2 } - 2 y ^ { 2 } } { x + y }$

Factor out $2$ in the numerator first and then factor again.
