y = 3x - 3
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...
