Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-56' to each side of the equation.
56 + -2y + -56 + y2 = 0 + -56

Reorder the terms:
56 + -56 + -2y + y2 = 0 + -56

Combine like terms: 56 + -56 = 0
0 + -2y + y2 = 0 + -56
-2y + y2 = 0 + -56

Combine like terms: 0 + -56 = -56
-2y + y2 = -56

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 = -56 + 1

Reorder the terms:
1 + -2y + y2 = -56 + 1

Combine like terms: -56 + 1 = -55
1 + -2y + y2 = -55

Factor a perfect square on the left side:
(y + -1)(y + -1) = -55

Can't calculate square root of the right side.
