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

Quadratic equations fall into an interesting donut hole in education. Students learn them beginning in algebra or pre-algebra classes, but they’re spoonfed examples that work out very easily and ...

Many former algebra students have painful memories of struggling to memorize the quadratic formula. A new way to derive it, overlooked for 4,000 years, is so simple it eliminates the need.

Before students are presented with the quadratic formula, they’re taught a simpler method to solve certain equations. For simplicity, we’ll consider an equation where a = 1. x ² – 4 x – 5 = 0 ...

Economist Glen Weyl says that he has a better idea: bolstering democracy with a few well-placed quadratic equations. Steven Levitt, of “Freakonomics” fame, calls Dr. Weyl’s proposal “so ...

A quadratic equation contains terms close term Terms are individual components of expressions or equations. For example, in the expression 7a + 4, 7a is a term as is 4. up to \(x^2\). There are ...

This is the cubic formula, which, like the quadratic formula, solves every cubic equation. But unlike the quadratic formula, it has no catchy tune to sing along to. You’re welcome to try to write one, ...

Learn about and revise quadratic equations by factorising, completing the square and using the quadratic formula with GCSE Bitesize OCR Maths.

Dr. Po-Shen Loh of Carnegie Mellon University (pictured above) stumbled on a simpler secondary equation that allows students to accurately solve quadratic equations without having to deal with the ...

But he systematically set out word-­form linear and quadratic equations, with algorithmic methods for solving them — that is, for finding the "unknown numbers," our modern x's and y's.
