Solving
56 + -1z + z2 = 0

Solving for variable 'z'.

Begin completing the square.

Move the constant term to the right:

Add '-56' to each side of the equation.
56 + -1z + -56 + z2 = 0 + -56

Reorder the terms:
56 + -56 + -1z + z2 = 0 + -56

Combine like terms: 56 + -56 = 0
0 + -1z + z2 = 0 + -56
-1z + z2 = 0 + -56

Combine like terms: 0 + -56 = -56
-1z + z2 = -56

The z term is -1z.  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.
-1z + 0.25 + z2 = -56 + 0.25

Reorder the terms:
0.25 + -1z + z2 = -56 + 0.25

Combine like terms: -56 + 0.25 = -55.75
0.25 + -1z + z2 = -55.75

Factor a perfect square on the left side:
(z + -0.5)(z + -0.5) = -55.75

Can't calculate square root of the right side.
