Solve by using the quadratic formula

First, put all the terms on one side.


x^2 + 7x -12 = 0

If the original sign for the 12 were negative, this would lead you to:

x^2 + 7x + 12 = 0

This could factor into:

(x+3)(x+4) = 0

However, as you have formula posted, it cannot be factored.

I hope this helps. Thanks for asking.
