in quadratic formula b2 4ac is called. It is to be noted that either of a b and c can be zero and still the equation would be called quadratic equation. Hence the expression b 2 4ac is called the discriminant of the quadratic equation ax 2 bx c 0.

Where the plus-minus symbol indicates that the quadratic equation has two solutions. But it does not always work out like that. Some examples of quadratics equations are x2 3x 4 0 X2 5x 0 x2 4 0.
The expression b 2 4ac is called the Discriminant of any given quadratic equation of the form ax 2 bx c 0.
This is called the quadratic formula which is. Each of these two solutions is also called a root or zero of the quadratic equation. If a and b is a source for a quadratic equations the equation will be. Below is an example of using the quadratic formula.
