Answer:

Step-by-step explanation:
To complete the square: add 4 to both sides because the product of 4 as 2 as the factor which 2 * 2 so 



Now we can factor the expression

Move the 4 to the other side to isolate y which changes the sign
Option C:

Solution:
Given expression:

To find which expression is equal to the given expression.

Expand the term 

Arrange the like terms together.


Factor the numerator 

Cancel the common factor g + 2, we get

Hence option C is the correct answer.
The sequence is all odd numbers. the next will be 15, 17, 19, 21, etc...
Y= -2x+3. This is the equation of the line.
