Solved by pluggable solver: SOLVE quadratic equation with variable

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=281 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 7.94076365356005, -0.440763653560053. Here's your graph:
