Given the equation:
(1)

We need to find a, b and c. So, we know that a quadratic equation is given by:
(2)

Then, we need to order the equation (1) and to adjust it to the equation (2), so:

So, if we compare these two equations, the conclusion is:



(3)

Substituiting a, b and c into (3):

Finally, the results are two values:
