As an example you can use it to calculate the length of the hypotenuse in a triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides.

As a formula a^2 + b^2 ...

Step 1: Find the highest common factor of the terms in the expression eg. 3x+12. In this expression 3 is the highest common factor of the terms 3x and 12...

The answer is P^7 because p is the same in both numbers and their powers need to be added up

My explanation would depend on the level of understanding of the person but one way would be the following:

We know that a = 2. Substitute the value of "a" in the given equation:

2...

We can see right off the bat that this is a quadratic equation. As always with quadratics, it is easiest to see if it factorises first. To factorise, you need to find two numbers that multiply together to...
