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=105 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 1.6234753829798, -8.6234753829798. Here's your graph:
