Homework Help: Math.

Posted by Claudia C. on Monday, December 1, 2008 at 7:56pm.

I need help with factoring polynomials using pi and sigma. I understand it, but what is the best way to find the sigma when the terms are, in my opinion, really large? It takes me forever to find it, guessing.
Let's say the problem is this:
56x² - 53xy + 12y²
The pi = 672 = (-____)(-_____)
and the sigma = -53 = (-__) + (-___)
How would you solve the problem?
