WebHow to factorise. In order to factorise, you need to find what amounts can be multiplied together to get an expression. Participants will need to find the highest common factor to find these common multipliers. It is the opposite of expanding. If you need a little refresher on the basics of factorising, check out the marvellous video below.
WebStep 4: Separate the terms to make two expressions to factorise: =x 2 - 2x + 3x - 6 =x 2 - 2x + 3x - 6 (make sure its +3x) Step 5: Factorise each expression =x 2 - 2x + 3x - 6 =x (x - 2) + 3 (x - 2) The contents of both the brackets should be the same! Step 6: Put the terms outside the bracket in one bracket, and the same bracket next to it. WebThe trick to factorising the difference of two squares is to use the formula, \textcolor {blue} {a^2 -b^2 = (a+b) (a-b)} This can be used in either direction to factorise or expand such expressions quickly. To show that this works, we will expand the two brackets of the general formula.
