Hello, I've decided to see if any of you can factor this eq. since it's not possible to have Mathematica show intermediate steps when factoring. This is a problem from my precalc book, and the instructor of the class hasn't been able to get to the final answer either. I've tried and tried using grouping in various ways, as well as other techniques. I'd appreciate it if anyone can figure this out, since I just can't get over this problem. Original problem: y^4 - (p + q)*y^3 + (p^2*q + p*q^2)*y - p^2*q^2 Answer in book: (y^2 - p*q)*(y - p)*(y - q) Thanks! --Steven
