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=97 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:
