Student Problem #5 Unit J Concept 5

Unit J Concept 5

• What is this problem about?

This problem goes over a problem from Unit J Concept 5. Unit J Concept 5 covers a lesson on Partial Fraction decomposition with distinct factors. This concept is much easier than it seems. There are 7 steps in which you must take to complete this problem and they are as follows: Factor out the denominator, separate each of the factors into their own fractions and put the letters A,B,C, etc. on top, get a least common denominator for the factors by multiplying it by what its missing, combine like terms, set the coefficients of the numerator equal to like term letters on the right, set up the system and solve, and finally put A, B,C, ect. back to where there variable is at in the spit up fractions in the beginning. 

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

The viewer needs to pay special attention not to forget to put zeroes in the numerator if there is just an x, or if something is missing. This is important because when setting up your system of equations you may forget and get confused of what number goes on the other side of the equal sign. Also, you must pay attention to how you take out the x's once writing your system. You need to be sure to take the x's out so that you can combine terms an solve for A or B, it is not necessary to keep those x's in the equations at this point.
