Given f(x)=x2−2x−2, completing the square to solve for the function's zeros yields which of the following? A. (x−1)2=−2 B. (x−2)

LekaFEV [45]

Answer:

(x-1)² = 3

Step-by-step explanation:

Given f(x)=x²−2x−2

Completing x²−2x−2 = 0 to square

x²−2x − 2=0
x²−2x + 1 - 3 =0
(x - 1)² - 3 = 0
(x - 1)² = 3

Correct choice is D

Solve the equation Square root of x minus 5+ 7 = 11 for the variable. Show each step of your solution process. (10 points)

Murrr4er [49]

$\sqrt{x - 5} + 7 = 11$

$(\sqrt{x-5}) ^{2} = (4)^{2}$

|x - 5| = 16

x - 5 = +/- 16

x - 5 = 16 or x - 5 = -16

<u> +5</u> <u>+5 </u> <u> +5 </u> <u>+5 </u>

x = 21 or x = -11

Answer: x = {21, -11}
