The first step of looking at a question like this is to highlight all the important information in the question. We are told that the square has an area of 64 cm² so what can we infer about the...

This is an example of a quadratic equation which we can solve on of two ways as it takes the form ax^2 + bx - c = 0a = 1, b = -5, c = -14 (1) Factorisation which we can do ourselves OR (2) Use the quadrat...

Firstly multiply the first equation by 2 resulting in the equation 12a + 2b = 32. Following this, add the first equation to the second equation, this will result in the 2b cancelling out with just 17a = 5...

In simultaneous equations, at this level, you are often given two equations both containing an x and a y. For example:Equation1: y + 2x = 3Equation2: 4y + 2x = 8.The first step in approaching this is to t...
