The question asks: Use the method of completing the square to express the solutions to each of these quadratic equations in the form a ± b √n, where a and b are rational and n is an integer:

y

^{2}- 2y - 1 = 0

(y-1)

^{2}- 2 = 0

(y-1)

^{2}= 2

y = 1 + √2

I know how to solve but I don't know how to recognize a and b in my answer.

Can anyone please explain?

Thanks
