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 doesn’t ...

In a boon to algebra students everywhere, a professor at Carnegie Mellon University has devised a simpler and more efficient way to solve problems involving the quadratic equation. The new method was ...

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 \(\frac{(-6 ...

Google's latest animated Doodle celebrates the quadratic equation, transforming its homepage into an interactive classroom.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The IRS’s job isn’t easy. But it’s hard to believe that their forms couldn’t be, well, a bit simpler. Daniel Velleman, a mathematician at Amherst College, clearly agrees. Back in 2007, he imagined the ...

Using the quadratic formula is another method of solving quadratic equations that will not factorise. You will need to learn this formula, as well as understanding how to use it. The first solution is ...
