So Then some simple rearranging gives Which means that the solution for a quadratic equation is: Voilà! That’s the quadratic formula. [The more general version can be derived by dividing the ...

A mathematician has derived an easier way to solve quadratic equation problems ... If students can remember some simple generalizations about roots, they can decide where to go next.

\(3x^2 = 48\) is an example of a quadratic equation that can be solved simply. If \((x + 1)(x + 2) = 0\), then \(x + 1 = 0\) or \(x + 2 = 0\), meaning \(x = -1\) or ...

which was supposed to be about making ‘something that was supposed to be complicated into something simple.’ In the typical quadratic equation--X2 - BX + C = 0—students would try and solve ...

{2a}$$ As intimidating as this looks, hiding inside is a simple secret that makes solving every quadratic equation easy: symmetry. Let’s look at how symmetry makes the quadratic formula work and how a ...

A mathematician and a computer scientist have just solved an "impossible" equation that has been considered unsolvable for centuries.
