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=1.69 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 1.66666666666667, -0.5. Here's your graph:
