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=2020 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 47.4722050542442, 2.52779494575577. Here's your graph:

--------------
--> 25 ± sqrt(505)
