Can be factored...

.
So the roots are x = 5 and x = -12.
.
Or by using the quadratic.

Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=289 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 5, -12. Here's your graph:
