Simplifying
16 + -4y + -4y + y + y2 = 2

Combine like terms: -4y + -4y = -8y
16 + -8y + y + y2 = 2

Combine like terms: -8y + y = -7y
16 + -7y + y2 = 2

Solving
16 + -7y + y2 = 2

Solving for variable 'y'.

Reorder the terms:
16 + -2 + -7y + y2 = 2 + -2

Combine like terms: 16 + -2 = 14
14 + -7y + y2 = 2 + -2

Combine like terms: 2 + -2 = 0
14 + -7y + y2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-14' to each side of the equation.
14 + -7y + -14 + y2 = 0 + -14

Reorder the terms:
14 + -14 + -7y + y2 = 0 + -14

Combine like terms: 14 + -14 = 0
0 + -7y + y2 = 0 + -14
-7y + y2 = 0 + -14
