If numerator polynomial has higher degree, divide polynomials to get quotient and remainder. Then integrate quotient, integrate remainder, and add results {ratios of polynomials integration}.
To integrate sum of functions {sum of functions integration}: Integral of |u(x) + v(x)| * dx = integral of u(x) * dx + integral of v(x) * dx. Integral of |u(x) - v(x)| * dx = integral of u(x) * dx - integral of v(x) * dx.
