Answer
$x^3-2x^2-10x-13$
Work Step by Step
Removing the grouping symbols and then combining like terms, the given expression, $
(4x^3-3x^2+2x-5)-(3x^3+11x+8)+(x^2-x)
,$ simplifies to
\begin{array}{l}\require{cancel}
4x^3-3x^2+2x-5-3x^3-11x-8+x^2-x
\\\\=
(4x^3-3x^3)+(-3x^2+x^2)+(2x-11x-x)+(-5-8)
\\\\=
x^3-2x^2-10x-13
.\end{array}
