I've been trying to figure this question out for a while, but I've never come across one like this before. Can anyone help to explain how I would answer this question?
Question: a) express x^2 - 4x + 1 in the form (x + a )^2 + b
b) hence solve the equation x^2 - 4x + 1 = 0 giving your answer in the form p +- sqrt q where p and q are integers
I managed to figure out part a) which was ( x - 2 )^2 - 3
any help with part b) would be really appreciated
