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

$h(s)=(-7s+6)(-8s+5)$

a$)$ Use the Product Rule, $[fg{]}^{\text{'}}=f*g^{\text{'}}+f^{\text{'}}*g.($Fill in each blank, then simplify.$)$

$h^{\text{'}}(s)=()*()+()+()$

$=$

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

$h^{\text{'}}(s)=$
