Homework Help: Pre-Calc/Trig

Posted by Sheila on Tuesday, September 6, 2011 at 5:05pm.

Please help-I'm stuck really bad
What are the roots of the equation x^2 - 4x + 3 = 0

I think I was suppose to use b^2 - 4ac
so it would be -4 - (-4)*1*3 = 12 so the roots would be 12 and -12
Thank you for any help you can provide
