12 + -12y + 5y2 = 0

Solving for variable 'y'.

Begin completing the square.  Divide all terms by
5 the coefficient of the squared term: 

Divide each side by '5'.
2.4 + -2.4y + y2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + -2.4y + -2.4 + y2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + -2.4y + y2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + -2.4y + y2 = 0 + -2.4
-2.4y + y2 = 0 + -2.4

Combine like terms: 0 + -2.4 = -2.4
-2.4y + y2 = -2.4

The y term is -2.4y.  Take half its coefficient (-1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
-2.4y + 1.44 + y2 = -2.4 + 1.44

Reorder the terms:
1.44 + -2.4y + y2 = -2.4 + 1.44

Combine like terms: -2.4 + 1.44 = -0.96
1.44 + -2.4y + y2 = -0.96

Factor a perfect square on the left side:
(y + -1.2)(y + -1.2) = -0.96

Can't calculate square root of the right side.

The solution to this equation could not be determined.
