Solving for variable 'z'.

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

Divide each side by '15'.
0.1333333333 + -0.2z2 + z4 = 0

Move the constant term to the right:

Add '-0.1333333333' to each side of the equation.
0.1333333333 + -0.2z2 + -0.1333333333 + z4 = 0 + -0.1333333333

Reorder the terms:
0.1333333333 + -0.1333333333 + -0.2z2 + z4 = 0 + -0.1333333333

Combine like terms: 0.1333333333 + -0.1333333333 = 0.0000000000
0.0000000000 + -0.2z2 + z4 = 0 + -0.1333333333
-0.2z2 + z4 = 0 + -0.1333333333

Combine like terms: 0 + -0.1333333333 = -0.1333333333
-0.2z2 + z4 = -0.1333333333

The z term is -0.2z2.  Take half its coefficient (-0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
-0.2z2 + 0.01 + z4 = -0.1333333333 + 0.01

Reorder the terms:
0.01 + -0.2z2 + z4 = -0.1333333333 + 0.01

Combine like terms: -0.1333333333 + 0.01 = -0.1233333333
0.01 + -0.2z2 + z4 = -0.1233333333

Factor a perfect square on the left side:
(z2 + -0.1)(z2 + -0.1) = -0.1233333333

Can't calculate square root of the right side.

The solution to this equation could not be determined.
