SP 4: Unit J Concept 4: Partial Fraction Decomposition with Distinct Factors

The trickiest part of this problem is decomposing the fraction back again. The student needs to pay attention to how to set up the problem using new variables, such as A, B, and C. The factoring and the distribution must all be correct, because one simply mistake in multiplication could cause the whole problem to be wrong. Finally, the student needs to set up the system of equations correctly using terms that correspond with one another, and then plug that system into the calculator to solve.
