U-substitution.

U = 6x4 − 3x

Before you integrate, factor the π out of the integrand. You may (or may not) choose to expand (x + 1)².

U-substitution.

You could long divide first or... use U-Substitution.
Let U = the denominator.

If U = x + 2 then x = U − 2.

Also bounds U(0) = 2 and U(− 1) = 1
Rewrite the integral and evaluate.

Recall that 9x² = (3x
Then look for a familiar antiderivative.
