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}
