Homework Help: Algebra

Posted by Peter on Monday, October 5, 2009 at 9:01pm.

When you're breaking down the square root in the quadratic formula into several parts- say it was the originally the square root of 80 so you break it down to square root of 4 and square root of 20-would the results be added or multiplyed? Because I know when you further break this down you get 2, the square root of five and the square root of four. Would you add the two 2's, or multiply them? And is there a +/- sign in front of each coefficient or is it just in front of the ACTUAL square root, not the broken down parts of the square root? Thank you so much for clarifying this!
