S is a geometric sequence. a) (1x + 1), 1 and (rootx - 1) are the first three terms of S.
Find the value of x.
You must show all your working.

b) The 5 term of S can be written in the form a V2 + b
where a and b are integers
Find the value of a and the value of b

At which value in the domain does f(x) =0?
