SP #5: Unit J Concept 6: Partial Fraction Decomposition With Repeated Factors

In this concept, students will be separating the fractions, in other word, decompose the fraction in order to solve for the variable. This concept is similar to concept 4, in which students need to find the common denominator and multiply the top and bottom by what it is missing and then solve for it by combining like terms and use elimination. However, in this concept, there is a repeated factors.

Students need to be carefu about the repeated factors. The repeated factors need to be listed up to a power. Example: the repeated factors is (x+3)^3 is written as (x+3)(x+3)(x+3)^3. Also students needs to be careful when foiling because of the negative signs. It can change your whole answer.
