Answer:
First, express the fraction in <u>partial fractions</u>
Write it out as an identity:
Add the partial fractions:
Cancel the denominators from both sides of the original identity, so the numerators are equal:
Now solve for A, B and C by <u>substitution</u>.
Substitute values of x which make one of the expressions equal zero (to eliminate all but one of A, B and C):
Replace the found values of A, B and C in the original identity:
Now integrate:
