Divide each side by '15'.
0.1333333333 + -0.4y + y2 = 0

Move the constant term to the right:

Add '-0.1333333333' to each side of the equation.
0.1333333333 + -0.4y + -0.1333333333 + y2 = 0 + -0.1333333333

Reorder the terms:
0.1333333333 + -0.1333333333 + -0.4y + y2 = 0 + -0.1333333333

Combine like terms: 0.1333333333 + -0.1333333333 = 0.0000000000
0.0000000000 + -0.4y + y2 = 0 + -0.1333333333
-0.4y + y2 = 0 + -0.1333333333

Combine like terms: 0 + -0.1333333333 = -0.1333333333
-0.4y + y2 = -0.1333333333

The y term is -0.4y.  Take half its coefficient (-0.2).
