Solving for variable 'z'.

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -1z4 + -1 + z8 = 0 + -1

Reorder the terms:
1 + -1 + -1z4 + z8 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1z4 + z8 = 0 + -1
-1z4 + z8 = 0 + -1

Combine like terms: 0 + -1 = -1
-1z4 + z8 = -1

The z term is -1z4.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1z4 + 0.25 + z8 = -1 + 0.25

Reorder the terms:
0.25 + -1z4 + z8 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + -1z4 + z8 = -0.75

Factor a perfect square on the left side:
(z4 + -0.5)(z4 + -0.5) = -0.75

Can't calculate square root of the right side.
