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=37 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 0.847127088383037, -1.18046042171637. Here's your graph:
