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
Answer: First Option

Step-by-step explanation:
Quadratic quadratic functions have the following form:

Where the point (h, k) is the vertex of the function.
For a quadratic function of the form
the vertex of the function is at the point 
In this case the function is: 
Then:

The vertex is:


Note that

Therefore the vertex is the point 
Finally we have that 
The function in vertex form is :

Answer:
the constant is the number without an x attaches to it.
Ex:
y = 2x + 9
9 is a constant because it is not attached to any x
y = x^3 + 2x^2 + 10x + 19
19 is a constant because it is not attached to any x
