Question 206375: The problem I am trying to figure out really has me stumped.I have to "factor completely" 185x^2 + 9x -2. I have tried grouping, GCF, FOIL, trial and error and I can't come up with anything any better than x(185x + 9)-2. Can you help me?

You can put this solution on YOUR website!
the discriminant for this expression (b^2 - 4ac), indicates that it is not factorable

1561 is NOT a perfect square, so the roots (and the factors) are NOT rational numbers
