In a proportional equation, you represent the factor of proportionality as k. In this case it means that y=kx^2. In the question you're given a number for both y and x. Sub these in in order to solve for ...

To begin with, answering this question requires basic knowledge of simple Mathematical function and ability to solve simultaneous equations. One thing you need to be able to do is recognising what kind of...

This question is more easily answered with the help of multiple diagrams, but:1) Draw a rectangle, and draw a line between the top left corner and the bottom right corner. This line divides the rectangle ...

When we factorise we basically want to put an equation into brackets.Firstly we need to see what can be taken out of both parts of the equation.Both 12 and 18 divide by 6. 12/6= 2 and 18/6 = 3So we can ta...

How to FACTORISE an equation:
To avoid confusion; x = xx = multiplication​Take the example; 3x +18
In order to factorise we need to find a common factor for both '3x' and '18' and this number wi...
