Expanding functions in increasing powers

[struglnstudnt]

I have not been taught how to do this and therefore unable to answer the following question :-

Expand the function f(x) = (1+x)^3 in increasing powers of x ?

Please help

Hi struglnstudnt!

You need to calculate

$$(1+x)^3=(1+x)(1+x)(1+x)$$

Just work out the brackets...
