Final answer:
To evaluate the integral and express the integrand as a sum of partial fractions, factor the denominator and set up the partial fraction decomposition. Solve for the unknown numerators and integrate each partial fraction separately to evaluate the integral.
Step-by-step explanation:
To evaluate the integral and express the integrand as a sum of partial fractions, you first need to factor the denominator. Once factored, set up the partial fraction decomposition by expressing the integrand as a sum of fractions with unknown numerators. The denominators of these fractions should match the factors obtained from factoring the original denominator. To find the unknown numerators, equate the original integrand to the sum of the partial fractions and solve for the unknowns. Finally, integrate each partial fraction separately to evaluate the integral.
