Partial fraction decomposition. Info from Algebra I: If numerator has lower degree than denominator and denominator is the product of all linear terms, then: Partial Fractions

Example 1 Evaluate: Since numerator has lower degree than denominator + + For x = 0: For x = -3: For x = 1: Thus; +C =

Example 2 Cover (x-1)!!! Evaluate: For A, set x = 1 For C, set x = 3 and cover x-3; OR For B, set x = 2 and cover x-2;

Example 3 Evaluate: For A, set x = 0 and cover x; For C, set x = -5 and cover x+5; For B, set x = 2 and cover x-2;

Example 4: Power of numerator is greater than denominator Evaluate:

Factor the denominator: Thus: If factored terms are not all linear:Example 5 (not in AP test) Note that in: Evaluate: Factor the denominator: Thus: Since C = -5; A = 3; B = 1 For C; Set x = ; C = -5;
