Compute the derivative of the given function in two different ways.

$h(x)=\frac{x^3-5x^2}{2x^2}$

a$)$ Use the Quotient Rule, $[\frac{f}{g}{]}^{\text{'}}=\frac{g*f^{\text{'}}-f*g^{\text{'}}}{g^2}.($Fill in each blank, then simplify.$)$

$$

$=$

b$)$ Use algebra first to simplify $h,$ then differentiate without the Quotient Rule.

$h^{\text{'}}(x)$
