The roots of a quadratic equation ax^2 + bx + c = 0 are given by `(-b+-sqrt(b^2 - 4ac))/(2a)`

If the roots are of the form X and X^2

`(-b + sqrt(b^2 - 4ac))/(2a) = ((-b-sqrt(b^2 - 4ac))/(2a))^2` if X > 1 and `(-b - sqrt(b^2 - 4ac))/(2a) = ((-b+sqrt(b^2 - 4ac))/(2a))^2` if X < 1

It is not possible to express the relation between the coefficients in a better way.
