The first step is to expand the expression. This can be done using the FOIL method. This means that we multiply the First, Outside, Inside and Last terms in the bracket.First: x . x = x²Outside...

When presented with an equation that involves x^2, it is likely to be a quadratic equation. This leads us to rearrange to the equation above into the form of ax^2 + b + c = 0. Therefore the equation ca...

This is an example of a quadratic equation. One way of solving it wwould be to use the quadratic formula. You can subsitute the values of a, b and c into the formula where a=1 b=3 and c=-10. This will ...

In order to find the lowest value for X we first need to find the lowest possible value for a and b.

Let us start off with a:

If a is the lowest possible cube number we can ...

We call 3! 'three factorial' and 5! 'five factorial'.

3!=3x2x1

5!=5x4x3x2x1

So our fraction becomes:

(3x2x1) / (5x4x3x2x1) = 6/120
