Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)

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=1300 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 0.721110255092798, -0.721110255092798. Here's your graph:
