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=124 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 8.56776436283002, -2.56776436283002. Here's your graph:

====================
It cannot be factored, ignore that statement.
