Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have ...

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 a ...

An animated guide to factorising quadratic expressions and equations. Examples are used to show how to find factors that multiply to give the number term and add to give the x coefficient in an ...
