Hi /sci/sqt/
I'm getting ready for a calculus test and today I am working on the partial fraction decomposition. Some questions will require me to complete the square in the denominator. When they do it here in the book, they get a more convenient solution to work with than I do. Can anyone point me in the direction to getting the result that they get when completing the square? I can prove that their answer is equivalent to mine, but I don't know how they got theirs
