Complete the square to transform the expression x^2− 2x − 2 into the form a(x − h)^2+ k.
(x − 1)2 + 3
(x − 1)2 − 3
(x − 2)2 − 3
(x − 2)2 + 3

(x - 1)² - 3

Step-by-step explanation:

Given

x² - 2x - 2

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² - 2x

x² + 2(- 1)x + 1 - 1 - 2

= (x - 1)² - 3

a)(x-2)^2+(y-1)^2=9
