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=133 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 3.08876043244513, -0.755427099111799. Here's your graph:
