Portia solved the quadratic equation x^2 + 2*sqrt(2)*x + 1 = 0 by completing the square. In the process, she came up with the equivalent equation

(x + r)^2 = s,

where r and s are constants. What is s?

x^2 + 2*sqrt(2)*x + 1 = 0      complete the square  ( take 1/2 of 'x' coefficient )

(x - sqrt2)2    - 2 + 1 = 0

(x -sqrt2)= 1
