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=1836009 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 1.99264163228685, -0.498156338169206. Here's your graph:

The solutions are 'close to the zeroes' in the original denominator, but not equal
