1. The problem statement, all variables and given/known data The question is stated at the top of the attached picture with a solution 20160303_095831.jpg The correct results of the coefficients are A=2, B=-5, C=1 I have tried this problem multiple times and am still getting ugly coefficients. I have no idea why. A fresh pair of eyes would be welcome. I have even had mathematica solve it for me to get some insight but it solves using matrices, which is not helpful when attempting it algebraically.
