Subproblem 1
Set the factor '(6 + -1z2)' equal to zero and attempt to solve:

Simplifying
6 + -1z2 = 0

Solving
6 + -1z2 = 0

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

Add '-6' to each side of the equation.
6 + -6 + -1z2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1z2 = 0 + -6
-1z2 = 0 + -6

Combine like terms: 0 + -6 = -6
-1z2 = -6

Divide each side by '-1'.
z2 = 6

Simplifying
z2 = 6

Take the square root of each side:
z = {-2.449489743, 2.449489743}
Subproblem 2
Set the factor '(2 + z)' equal to zero and attempt to solve:

Simplifying
2 + z = 0

Solving
2 + z = 0

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

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

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

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

Simplifying
z = -2
Subproblem 3
Set the factor '(2 + -1z)' equal to zero and attempt to solve:

2 + -2 + -1z = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -1z = 0 + -2
-1z = 0 + -2

Combine like terms: 0 + -2 = -2
-1z = -2

Divide each side by '-1'.
z = 2

Simplifying
z = 2
Solution
z = {-2.449489743, 2.449489743, -2, 2}
