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=137 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 5.67617497767991, -0.176174977679906. Here's your graph:

------
= (11/4) �sqrt(137)/4
