Discriminant Formule D=0

Discriminant Formule D=0. A discriminant is a value calculated from a quadratic equation. The discriminant is the part of the quadratic formula underneath the square root symbol:

Now, observe that the discriminant is equal to the expression within the square root of the quadratic formula. This is the expression inside the square root of the quadratic formula. The discriminant is the expression found under the square root part of the quadratic formula (that is,.

This is a very important property because we can define a discriminant, with this same property, also for polynomials of any degree.

Lets see how to do it. However to derive it, we need quadratic formula (polynomial) is of type ax^2+bx+c where a, b and c are constants where a<>0. It use it to 'discriminate' between the roots (or solutions) of a quadratic equation. The discriminant is the expression found under the square root part of the quadratic formula (that is,.
