Basic simplification leads to the following answer:

$x^3+x^2-52x-24$

By using basic distributive law:

$= (x+8)(x^2 -7x-3)$

$=(x*x^2)+(x*-7x)+(x*-3)+(8*x^2)+(8*-7x)+(8*-3)$

yields

$x^3 - 7x^2 - 3x + 8x^2 -56x -24$

Simplifying that further by collecting like terms gets you the final answer:
$x^3+x^2-52x-24$
