b^2-4ac is found in the quadratic formula. It is known as the determinent because if b^2-4ac>0, the equation has 2 distince real roots; id b^2-4ac=0 there is 1 repeated root; if b^2-4ac<0, there are 2 complex roots.

The quadratic formula. The discriminant would just be the b^2 - 4ac part. That is the entire formula minus x = [-b......

The value of what you just decsribed is called the discriminant.
The algebraic expression is called the quadratic formula, used to find the roots of any quadratic equation.
