Student Problem #6 Unit J Concept 6

• What is this problem about?

This problem covers an example from Unit J Concept 6. This concept is very similar to Concept 5 except now we are dealing with Partial Fraction Decomposition with repeated factors. In this type of problem when you try in factor the denominator out you will find that one of the factors is repeated. Meaning that now when you separate the factor into separate equations for the repeated factor you must include the factor as a denominator as many times as the exponent. For example if the denominator as shown is (x-1)^3 you must have one fraction be A/(x-1), the nest one be B/(x-1)^2, and the last one be C/(x-1)^3. This is the only difference, then you would just solve as you did in concept 5. 

• What does the viewer need to pay special attention to in order to understand the concept?

In this concept the viewer must pay special attention to the common denominator so that when multiplying the numerator by what a part of the fraction is missing then your system comes out to being correct. Also, you must pay attention to how to right the denominators when separating the fractions. You must also pay close attention making sure your answers are plugged in correctly in the end.
