SP #5: Unit J Concept 6 (partial decomposition/repeating factors)



 
The trickiest part of doing a partial decoposition problem with repeating factors is distinguishing the difference between one problem with distinct factors. We always have to start of by getting the least common denominator and multiplying the same to both top and bottom for each different part. After combining like terms and simplifying, remember to use those systems and plug them into a matrix. Matrices can be very tricky because although it can be easy, the steps are very easy to mess up. At the end it is crucial to go back and check your problems answer.

SP #4: Unit J Concept 5 (partial fraction decomposition with distinct factors)





The trickiest part of this problem would be to follow the appropriate steps accordingly. Make sure that whatever is multiplied to the bottom of a fraction must always be multiplied to the top. Also, it is easy to forget or confuse coefficients. Go back and check all distributions and simplifying.

SV #5: Unit J Concept 3-4 (finding values using matrices)



Matrices can be very confusing to solve. First we have to make sure we simplyify the equations before moving on. Also, make sure that you copy down the correct COEFFICIENTS because if one value is wrong, the entire solution is. The other tricky part is canceling out to get zeroes and ones because it although they are simple steps, it's easy to make a mistake.
