What is the standard form of a quadratic equation?

A quadratic equation in standard form is written as ax² + bx + c = 0, where a, b, and c are constants.

What are the solutions to a quadratic equation called?

The solutions to a quadratic equation are the values of x that make the equation true. They are also known as the roots or zeros of the equation.

What is the vertex form of a parabola?

The vertex form of a parabola is given by y = a(x - h)² + k, where (h, k) represents the coordinates of the vertex.

What is the vertex of a parabola?

The vertex of a parabola is the point where the parabola changes direction. It can be found using the formula x = -b/2a for the x-coordinate.
