SP 5: Unit J Concept 6: Partial Fraction Decomposition with Repeated Factors
The viewer needs to pay attention to a few things throughout the problem. The first is that they count up when creating "A, B, and C!" Also, they must combine the like terms correctly and properly distribute the variables. Lastly, when finding common denominators, they viewer must make sure that they are multiplying by the right factors! Good luck!

SP #4: Unit J Concept 5: Partial Fraction Decomposition with Distinct Factors
While doing these types of problems, the viewer has to pay attention to detail! Mixing up positives and negative can affect the entire problem! Also, when finding common denominators, the viewer needs to make sure that they FOIL the factors correctly.Lastly, when choosing variables, you must avoid "X" because it already plays a role in the problem! Thanks for viewing and good luck.

SV5: Unit J Concepts 3-4: solving three-variable systems using Gauss-Jordan elimination/matrices/row-echelon form/back-substitution and solving non square systems
to watch my video, please click HERE
Some of the most important things that the solver needs to pay attention to are the positive and negative signs! One mistake can throw off the entire problem. Also, they should make it a point to keep track of what they are doing to each row by writing it down on the line next to it. One of the last things they should make sure to pay attention to is that when back substituting, they do not mic up the value or place them in the wrong order(in the ordered triple)
