WebFeb 10, 2024 · A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. [1] There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. WebIf the discriminant is 0, then there can be only 1 root, -b/2a, +/-0, which must be subtracted from x in both of the binomial factors of the quadratic; so both factors are identical and we get a perfect square. The vertex form of the equation is (x-r)^2 + 0 = 0. The y coordinate of the vertex is 0. Comment ( 7 votes) Upvote Downvote Flag more
