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

Divide each side by '7'.
0.2857142857 + -2z + z2 = 0

Move the constant term to the right:

Add '-0.2857142857' to each side of the equation.
0.2857142857 + -2z + -0.2857142857 + z2 = 0 + -0.2857142857

Reorder the terms:
0.2857142857 + -0.2857142857 + -2z + z2 = 0 + -0.2857142857

Combine like terms: 0.2857142857 + -0.2857142857 = 0.0000000000
0.0000000000 + -2z + z2 = 0 + -0.2857142857
-2z + z2 = 0 + -0.2857142857

Combine like terms: 0 + -0.2857142857 = -0.2857142857
-2z + z2 = -0.2857142857

The z term is -2z.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2z + 1 + z2 = -0.2857142857 + 1

Reorder the terms:
1 + -2z + z2 = -0.2857142857 + 1

Combine like terms: -0.2857142857 + 1 = 0.7142857143
1 + -2z + z2 = 0.7142857143

Factor a perfect square on the left side:
(z + -1)(z + -1) = 0.7142857143

Calculate the square root of the right side: 0.845154255

Break this problem into two subproblems by setting 
(z + -1) equal to 0.845154255 and -0.845154255.

Subproblem 1
z + -1 = 0.845154255

Simplifying
z + -1 = 0.845154255

Reorder the terms:
-1 + z = 0.845154255

Solving
-1 + z = 0.845154255

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '1' to each side of the equation.
-1 + 1 + z = 0.845154255 + 1

Combine like terms: -1 + 1 = 0
0 + z = 0.845154255 + 1
z = 0.845154255 + 1

Combine like terms: 0.845154255 + 1 = 1.845154255
z = 1.845154255

Simplifying
z = 1.845154255

Subproblem 2
z + -1 = -0.845154255

Simplifying
z + -1 = -0.845154255
