Equation ii is fine and (4,0) is the only pair of solutions so if i) is your answer then it's correct
x^2 - 8x + 16 factors into (x-4)^2, so i) and ii) would both work. =)
However, as an answer to the problem, only x= 4, y= 0 is correct.
The equation x^2- 8x+ 16= 0 is a step on the way to finding the solution.
