Add Yahoo as a preferred source to see more of our stories on Google. Quadratic equations are polynomials that include an x², and teachers use them to teach students to find two solutions at once. The ...

For tips on how to do this, look at Factorising quadratics and Factorisation of further quadratics in this guide. For (\({x}\) + 2)(\({x}\) + 7) to equal 0 either the first or second bracket must be ...

Removing brackets is to multiply the term outside the brackets by each term inside - also known as the distributive law. Use FOIL to remove a pair of brackets then simplify by collecting like terms.
