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=465 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 0.0939764421413039, -7.0939764421413. Here's your graph:
