First, <=t's rewrite the denominator: x^n+1 - x = x(x^n - 1) So our integral becomes: x(x^n-1) dx

Using partial fractions: x(x^n-1) = Ax + Bx^n-1 Multiplying all terms by x(x^n-1): = A(x^n-1) + Bx When x = 0: = A(-1), so A = - When x = 1: = B, so B = Therefore: x^n+1-x = -x + x^n-1

Integrating each term: x^n+1-xdx = -xdx + x^n-1dx = -|x| + 1x^n-1dx

For the second integral, use substitution t = x^n: dt = nx^n-1dx → dx = dtnx^n-1 1x^n-1dx = 1t-1 dtnx^n-1 Since x^n-1 = tx, we have: 1x^n-1dx = 1n xt(t-1)dt
