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

A parabola is a symmetrical, curved, U-shaped graph. The equation of a parabola graph is y = x² Parabolas exist in everyday situations, such as the path of an object in the air, headlight shapes ...

A parabola is a symmetrical curve that can describe the path of a projectile, like a thrown football, or the curve of a suspension bridge. Parabolas are defined with variations on the equation y = x2.

The parabola, as any high school student should know, and I hope does know, you get a parabola if you take the equation y2=ax2a, is a constant. A catenary is a much more complicated equation.

A teenager from Gippsland in Victoria has written an equation that has been published in a national academic journal — a major achievement for one so young.

Solutions to the simplest polynomial equations — called “roots of unity” — have an elegant structure that mathematicians still use to study some of math’s greatest open questions.
