Solving
49 + 13y + y2 = 0

Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-49' to each side of the equation.
49 + 13y + -49 + y2 = 0 + -49

Reorder the terms:
49 + -49 + 13y + y2 = 0 + -49

Combine like terms: 49 + -49 = 0
0 + 13y + y2 = 0 + -49
13y + y2 = 0 + -49

Combine like terms: 0 + -49 = -49
13y + y2 = -49

The y term is 13y.  Take half its coefficient (6.5).
Square it (42.25) and add it to both sides.

Add '42.25' to each side of the equation.
13y + 42.25 + y2 = -49 + 42.25

Reorder the terms:
42.25 + 13y + y2 = -49 + 42.25

Combine like terms: -49 + 42.25 = -6.75
42.25 + 13y + y2 = -6.75

Factor a perfect square on the left side:
(y + 6.5)(y + 6.5) = -6.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
