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 ...

If you studied algebra in high school (or you're learning it right now), there's a good chance you're familiar with the quadratic formula. If not, it's possible you repressed it. By this point, ...

Here are some examples of quadratic equations in this form: \(2x^2 - 2x - 3 = 0\). \(a = 2\), \(b = -2\) and \(c = -3\) \(2x(x + 3) = 0\). \(a = 2\), \(b = 6\) and ...

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 ...

In this section, you will: * Solve linear trigonometric equations in sine and cosine. * Solve equations involving a single trigonometric function. * Solve trigonometric equations using a calculator. * ...

Do you remember solving quadratic equations? A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with ...

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 ...

Solving one of the oldest algebra problems isn't a bad claim to fame, and it's a claim Norman Wildberger can now make: The mathematician has solved what are known as higher-degree polynomial equations ...
