Quadratic equation

____ is the formula x=-b±b2-4ac2a, used to find the solutions to a quadratic equation of the form ax2+bx+c=0.

Quadratic formula

is an inequality of the form ax2+bx+c<y where a,b, and c are real numbers and a≠0, or any similar form with ≤,>, or ≥.

Quadratic inequality

____ is the expression, b2-4ac, which tells the nature of the roots of a quadratic equation of the form ax^2+bx+c=0.

The discriminant

Find the discriminant to determine the number of roots, then solve the quadratic equation using the quadratic formula. x^2+x-2=0
