Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)

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=260 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 5.06225774829855, -11.0622577482985. Here's your graph:

=============================
The 2 solutions are the 2 numbers.
