Plotting your graph A quadratic equation is represented as a curve on a set of axes. In order to draw the curve on a graph we require several pairs of coordinates.

Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have one or many variables in any combination, and the magnitude of them is ...

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.
