Answer

$p(x)=2x^2+5x+7$.

Work Step by Step

Write the equation. $\Rightarrow \frac{p(x)}{x-4}=2x+13+\frac{59}{x-4}$ Multiply the equation by $(x-4)$. $\Rightarrow (x-4)\left (\frac{p(x)}{x-4} \right )=(x-4) \left ( 2x+13+\frac{59}{x-4} \right )$ Using the distributive property on the right hand side: $\Rightarrow p(x)=(x-4) (2x+13)+(x-4)\left (\frac{59}{x-4} \right )$ Simplify by using the FOIL method. $\Rightarrow p(x)=2x^2+13x-8x-52+59$ Add like terms. $\Rightarrow p(x)=2x^2+5x+7$.
