Solution for z*z-z=44 equation:


Simplifying
z * z + -1z = 44

Multiply z * z
z2 + -1z = 44

Reorder the terms:
-1z + z2 = 44

Solving
-1z + z2 = 44

Solving for variable 'z'.

Reorder the terms:
-44 + -1z + z2 = 44 + -44

Combine like terms: 44 + -44 = 0
-44 + -1z + z2 = 0

Begin completing the square.

Move the constant term to the right:

Add '44' to each side of the equation.
-44 + -1z + 44 + z2 = 0 + 44

Reorder the terms:
-44 + 44 + -1z + z2 = 0 + 44

Combine like terms: -44 + 44 = 0
0 + -1z + z2 = 0 + 44
-1z + z2 = 0 + 44

Combine like terms: 0 + 44 = 44
-1z + z2 = 44

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 = 44 + 0.25

Reorder the terms:
0.25 + -1z + z2 = 44 + 0.25

Combine like terms: 44 + 0.25 = 44.25
0.25 + -1z + z2 = 44.25

Factor a perfect square on the left side:
(z + -0.5)(z + -0.5) = 44.25

Calculate the square root of the right side: 6.652067348

Break this problem into two subproblems by setting 
(z + -0.5) equal to 6.652067348 and -6.652067348.

Subproblem 1

z + -0.5 = 6.652067348 Simplifying z + -0.5 = 6.652067348 Reorder the terms: -0.5 + z = 6.652067348 Solving -0.5 + z = 6.652067348 Solving for variable 'z'.
