How to work with Algebra: Part 4

Blackboard with pneumonoultramicroscopicsilicovolcanoconiosis

At 45 letters, “pneumonoultramicroscopicsilicovolcanoconiosis” , which refers to a lung disease, is considered by some to be the longest word in English. It is, however, a made up word, invented in 1935 by the president of the National Puzzlers’ League of the United States, Everett E. Smith, in a presentation about the ever-growing length of medical terms.

There are definitely better ways to put those letters to good use!!!  You guessed it – more algebra to practise!!

Try out Part 4 of our “How to” Algebra guides. This week covers factorising quadratics, which means “putting it into 2 brackets”.

The standard format for quadratic equations is

Quadratic equation

This guide will show you methods of factorising when ‘a’ = 1, and when ‘a’ is not 1 (which is a bit trickier!). It will also take you through how to solve quadratic equations after factorising them.

There are some example questions for you to measure your progress, and answers are provided for you to check your understanding.
