WebFor a quadratic equation of the form, a x 2 + b x + c = 0, the Quadratic Formula is x = - b ± b 2 - 4 a c 2 a. The Discriminant is used to find the number and type of solutions a quadratic equation has. It is given by the formula D = b2 - 4ac. The conditions for the discriminant are summarized in the following table. WebThe Discriminant - Concept. The discriminant is the term underneath the square root in the quadratic formula and tells us the number of solutions to a quadratic equation. If the discriminant is positive, we know that we have 2 solutions. If it is negative, there are no solutions and if the discriminant is equal to zero, we have one solution.
