By putting the -1 in the square brackets.
Move it off to the end of the line before you start, and hopefully things will be clearer.

yes need to leave the -1 to one side & factorise the other bits.
This still does not make any sense to me... maybe illustrate it?

which should be a pretty common result to know if you know about factorials.
so by definition.

factorials is just the product of the numbers from 1 up to where you are.
so if you have ( k + 1 )! then times by the next number above, you get ( k + 2 ) !
