Answer:
(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
The given expression x² − 2x − 2 is equivalent to the expression (x − 1)² − 3. Then the correct option is B.
What is an equivalent function?
The equivalent is the functions that are in different forms but are equal to the same value.
The expression is given below.
→ x² − 2x − 2
Then the expression can be written as
Add and subtract one. Then we have
→ x² − 2x + 1 − 1 − 2
→ x² − 2x + 1 − 3
→ (x − 1)² − 3
The given expression x² − 2x − 2 is equivalent to the expression (x − 1)² − 3.
