So here its similar principle to the previous question but the only difference is that there are no singular y's.So essentially the question reads : y^2 + 0y - 64So in the same way we need factors of 64 t...

Factorising Quadratics, double bracketsWe want two numbers that multiply to give 8 and add to give 6. Lets list the factors of 8: 1, 2, 4, 8From the list of of numbers above, which 2 can add to give +6?2 ...

Below is the solution to the aforementioned question. In order to solve a simultaneous equation, one has to write one of the unkown variables in terms of the other. In this case, x was already written in ...

a) The gradient of a line is given by the equation (change in y)/(change in x). Therefore to find the gradient of the line in part a we must do (12-9)/(3-0) = 1. Now we have the gradient we can use the fo...

Simplify 125^-2/3
A negative indices means that we need to reciprocate the number or "flip it":
125^-2/3 = (1/125)^2/3
A fractional indices can be sp...
