WebYou can use the Quadratic Formula any time you're trying to solve a quadratic equation — as long as that equation is in the form "(a quadratic expression) that is set equal to zero". Often, the simplest way to solve "ax 2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor ... 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
