The first picture shows how to compose a partial fraction. The second picture shows how to decompose the result of the composed problem in order to eventually end up with the original partial fraction we started out with to compose. Both problems require a lot of distribution and factoring.
It's important to make sure to carefully factor and distribute because there is a lo of factoring and distributing. When decomposing, it;s crucial to remember to take out the x^2 and x in the combined equations. Also, the decomposition part of it requires a matrix to show the steps. When using the matrix part, use a graphing calculator properly by pressing 2nd matrix, edit, plug in the matrix values where they go, 2nd, quit, 2nd matrix, math, scroll down o rref(, select it, 2nd matrix, enter, close off with the end parentheses, enter, and that's the answer.
