Quadratic equation with quadratic coefficient a, linear coefficient b, and constant coefficient c. Common way to represent a quadratic (as well as sometimes with the square completed, or with a quadratic coefficient and roots)
ax^2 + bx + c <=> 2ax = b + sqrt(discriminant) or b - sqrt(discriminant), where the discriminant equals b*b - 4*a*c
