The factor theorem helps us to find factors of polynomial equations, by substituting in number values for x to see whether the equation equals zero. For any polynomial P(x), the factor theorem would state...

I have been struggling with maths when my teacher failed to teach me how to understand maths and only made me do the homework and tests. Maths is all about understanding the logic behind the calculations,...

A turning point on a curve will be a point where the curve is flat/horizontal i.e. where it has a gradient of zero. We know that to find the equation for the gradient of a curve we have to differentiate i...

This is an example of a common Mechanics 1 question. I teach a systematic approach to such questions. 

1. Diagram - dram diagram of the pulley set up

2. Label forces on diagra...

Label the equations 1 and 2 We want to make it so the x are the same number - therefore we have to find a common multiple of 2 and 3 - this is 6 Therefore the equations turn into: 1) 6x + 10y = -8 2) -6x ...
