x^2= 4(x^2 - 6x + 9)

x^2= 4x^2- 24x + 36

3x^2 - 24x + 36= 0

(x-2)(x-6)=0

x= 2 or x=6

Use the factorisation method.

Step 1: Rewrite (x + __ )(x + __ ) = 0

Step 2: We need to fill in the blanks. The numbers we require are -2 and -9.

Step 3: We need the values of x, so t...

(Depending on what the pupil wants to get out of this session and their ability I will explain the background of simultaneous equations and draw a graph of two lines and sho that their intersection is the...

Solving simultaneous equations by elimination; firstly you would multiply the first equation by 4 to get another equation which we will name (3), and multiply the second equation by 3 to get another equat...

We need to find numbers that multiply together to give -15. This could be -1 and 15, 1 and -15, -3 and 5, 3 and -5. The numbers we need must add up to -2 as well (from -2x term). Therefore our set must be...
