what is another word for the solution of a quadratic equation?
quadratic formula
because the quadratic equation involves only one unknown, it is called "univariate". the quadratic equation only contains powers of that are non-negative integers, and therefore it is a polynomial equation. in particular, it is a second-degree polynomial equation, since the greatest power is two.

a quadratic equation with real or complex coefficients has two solutions, called "roots". these two solutions may or may not be distinct, and they may or may not be real.

it follows from the quadratic formula that









































in the special case where the quadratic has only one distinct root ("i.e." the discriminant is zero), the quadratic polynomial can be factored as
