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
