Can someone please help me with my factoring problem.

I'm stuck and don't think I know how to solve this one. Can you please explain how to do it.

9x^2+7x-56

9x^2 + 7x - 56 = 0 cannot be factored, so you need the quadratic formula to solve it:

x = (-a ± sqrt(b^2 - 4ac))/(2a)
x = (-7 ± sqrt(2065))/18
x = 2.13568, -2.91346

9x^2+7x-56
x(9x+7)-56

Hope this helps!
