What Dunelm has put in his answer is correct. You will need to refer to the formula sheet and look for a particular expression which looks like (n r) a^(n - r) b^r and then find out what expressions a and b are.
Subsequently, you will need to use the rules of indices or some other method to combine the two expressions in x as a single power of x. Your working will end once you have obtained a single power of x.
