9-60.

Evaluate: $\lim\limits _ { h \rightarrow 0 } \frac { 2 ( 3 + h ) ^ { 2 } - 18 } { h }$

$\lim\limits_{h\rightarrow 0}\frac{2(9+6h+h^{2})-18}{h}$

At some point in your simplification, you should be able to factor an $h$ out of the terms in the numerator. This will make a Giant One with the $h$ in the denominator.
