6 + -2y + y2 = 0

Solving
6 + -2y + y2 = 0

Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -2y + -6 + y2 = 0 + -6

Reorder the terms:
6 + -6 + -2y + y2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -2y + y2 = 0 + -6
-2y + y2 = 0 + -6

Combine like terms: 0 + -6 = -6
-2y + y2 = -6

The y term is -2y.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2y + 1 + y2 = -6 + 1

Reorder the terms:
1 + -2y + y2 = -6 + 1

Combine like terms: -6 + 1 = -5
1 + -2y + y2 = -5

Factor a perfect square on the left side:
(y + -1)(y + -1) = -5

Can't calculate square root of the right side.
