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...

first of all, have a look at each side separately to see you you can cancel anything down.e.g. the square and square root can cancel out. => sq.root(6²+8²) = 6+8on the otherside, ...
