## Description

the discriminate used to fing the number of real solutions a quadratic equation will have

used to find the x coordinate of the vertex of a parabola

x=-b/2a

(b/2)^2

x=-b+-squareroot b^2-4ac/2a

b^2-ac

## Explanation & Answer

x = -b/2a is the x-coordinate of the vertex of the parabola;

b^2 - 4ac is the formula for the discriminant of the parabola;

x = - b +/- sqrt(b^2- 4ac) is the formula to find the roots of the equation of the parabola, or to find the x-coordinate of the intersection of the parabola with the x-axis;
