Look at the National 4 factorising section before continuing. When a question asks you to 'solve' a quadratic equation, this means that you are to find the roots of the quadratic. In other words ...

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 ...

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 ...

In high school, you may have encountered the quadratic formula, which gives solutions to equations where the unknown variable ... complex numbers make seemingly impossible integrals easy to solve and ...
