when multiplying indices you need to add the powers (only if the base number is the same -> need to ensure they are denoted with the same letter)

4 + 3 = 7

First, you must remember what the midpoint formula is for a line with two points.

M= ((x_1​+x_2​)/2 ​,(y₁​+y_2​​)/2)

Then apply it to this question.<...

The first step would be to consider each of the powers individually, work out their value and then proceed with the subtraction to end up with a result. Firstly, as this question is to be done without a c...

Factorise means we want to turn x²-8x+15=0 into the form (x+a)(x+b)=0. We need to find the two whole numbers 'a' and 'b' which equal -8 (from the -8x part) when added together,...

An arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. We can work this out for the sequence 11, 17, 23, 29. ...
