Read the question and translate the information into equations.'Three pens and one pencil for £11' can be written as 3x + y = 11 where x = pens and y = pencils. 'Four pens and two pencils for £16' can be ...

In a quadratic equation the highest power is 2. This means that we are looking for up to 2 answers. The first thing we are going to try to do is factorise the equation. We draw two sets of brackets side b...

Find the highest common factor between the brackets and then divide by this:in this case it is (m+3)so working out should look like this:(m-7)(m+3)/(m+3)/6(m+3)/(m+3)this will work out as:m-7/ 6

This is a question based on the application of Pythagoras. In the question a diagram of the triangle ABC will be provided and we would be able to see that we would need to work out the hypotenuse. Thus us...

y=x^2+5x+4 y=-3x-8 Equate the two equations: x^2+5x+4 = -3x-8Rearrange so that all values are on one side: x^2+8x+12=0 Factorise the equation by finding...
