-6 + 3y + -2y2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
3 + -1.5y + y2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -1.5y + -3 + y2 = 0 + -3

Reorder the terms:
3 + -3 + -1.5y + y2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1.5y + y2 = 0 + -3
-1.5y + y2 = 0 + -3

Combine like terms: 0 + -3 = -3
-1.5y + y2 = -3

The y term is -1.5y.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5y + 0.5625 + y2 = -3 + 0.5625
