This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

A mathematician has derived an easier way to solve quadratic equation problems, according to MIT's Technology Review. You love challenging math problems. So do we. Let's solve them together.

Invented by Leonardo Torres in 1920, the Torres calculating machine is a machine that solves essential addition, subtraction, ...

Everyone learns (and some readers maybe still remember) the quadratic formula. It’s a pillar of algebra and allows you to solve equations like Ax 2 +Bx+C=0. But just because you’ve used it ...

that this very complex structure emerges from such simple rules,” said Matthew Baker of the Georgia Institute of Technology. “It’s one of the really surprising discoveries of the 20th century.” There ...

The quadratic formula for a quadratic equation in the form of \(ax^2 + bx + c = 0\) is \(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\). The first solution is \(x = \frac ...

Save guides, add subjects and pick up where you left off with your BBC account. Here are some examples of quadratic equations in this form: \(2x^2 - 2x - 3 = 0\). \(a = 2\), \(b = -2\) and \(c ...
