In this video I work through 68 examples of factoring quadratic expressions when a is not equal to one. The first couple of ...

In a quadratic expression, the highest power of \(x\) is \(x^2\). Factorise \(x^2 + 7x + 10\). To factorise this expression, find two numbers that have a product of +10 and a sum of +7. There are four ...

Certainly! Here's the revised description with the links removed: --- So what I'd like to do is show you how to solve a ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas. His ...
