Hi,
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:
y2 - 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
