Axis Of Symmetry

A line that goes down the middle of the parabola and intersects the vertex

Quadratic Inequalities

A quadratic inequality is just like a quadratic equation, except instead of an equal sign there's an inequality

Quadratic Formula

Formula to find the zeroes of a quadratic equation.

Imaginary Number/ Complex Solution

If a quadratic equation with real-number coefficients has a negative discriminant, then the two solutions to the equation are complex conjugates of each other.

Completing the Square

Process to find the zeroes of a quadratic equation.

Standard Form

The standard form of a quadratic is y = ax ^2 + bx + c, where a, b, and c are numbers and a cannot be 0.

Vertex Form

The vertex form of a quadratic equation is written like f (x) = a(x - h)2 + k, with the letter h and the letter k being the vertex point of the parabola. It can be used to create an equation when the vertex of the parabola is known, but other points are not.

Maximum

The vertex if the parabola opens down.

Minimum

The vertex if the parabola opens up.

X value of X- intercept
