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=10 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 6.16227766016838, -0.16227766016838. Here's your graph:
