$($a$)$ Decompose the following function into partial fractions.

Your answer should be written as the sum and$/$or difference of the fractions, including the values of $A,B,$ and $C.$

$\frac{18y}{y^3-y^{2}y-1}=$

$($b$)$ Use your answer in part $($a$)$ to evaluate the following integral.

Remember to use absolute values where appropriate. Use C for the constant of integration.

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}\frac{18y}{y^3-y^{2}y-1}dy=$
