1. -3x²+4x+4 = 0 using factorisation find the quadratic in the form (-3x+a)(x+b)=0 find two numbers (a and 3b) that have a product of 4 and a sum of 4 a =2 and 3b =2 ➔ a =2 and b =2/3 (-3x+2...

The student should first draw a diagram of the pyramid, labelling the lengths of the base and the height. The student is not able to solve this problem in one step but must think two steps ahead. The stud...

factoring gives form n(n+1)(n-1) from here it should be realised that if n is not a multiple of 3 then n-1 is or n+1 is as multiples of 3 go up in 3s. Hence one of the values either n,n-1 or n+1 must be m...

This question explores surds. To find the area of a rectangle we must multiply its two sides together. When multiplying surds we follow the rule that roota x roota = rootaxa, therefore in this case by mul...

(9-x)/2 = 2x - 8 Firstly, we want to multiply both sides by two to get rid of the fraction:9-x = 2(2x - 8)Open up the brackets:9 - x = 4x - 16Finally, we want to get the x's on one side and the numbers on...
