Question 864277: This is about Linear Quadratic Systems. How do I pull out the GCF for x^2-2x-13 ?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
The GCF of x^2, -2x, -13 is 1 since this is the only factor that is common in all 3 terms. Since 1 is a trivial factor, there is nothing really to factor out.

Furthermore, there are no two numbers that both multiply to -13 and add to -2. So you cannot factor x^2-2x-13

If you wanted to solve x^2-2x-13 = 0, you would have to either complete the square or use the quadratic formula.
