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=3369 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:
