Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-35' to each side of the equation.
35 + -2y + -35 + y2 = 0 + -35

Reorder the terms:
35 + -35 + -2y + y2 = 0 + -35

Combine like terms: 35 + -35 = 0
0 + -2y + y2 = 0 + -35
-2y + y2 = 0 + -35

Combine like terms: 0 + -35 = -35
-2y + y2 = -35

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 = -35 + 1

Reorder the terms:
1 + -2y + y2 = -35 + 1

Combine like terms: -35 + 1 = -34
1 + -2y + y2 = -34

Factor a perfect square on the left side:
(y + -1)(y + -1) = -34

Can't calculate square root of the right side.
