3z^2+3z+3=0

Solution for 3z^2+3z+3=0 equation:

Simplifying
3z2 + 3z + 3 = 0

Reorder the terms:
3 + 3z + 3z2 = 0

Solving
3 + 3z + 3z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '3'.
3(1 + z + z2) = 0

Ignore the factor 3.
Subproblem 1
Set the factor '(1 + z + z2)' equal to zero and attempt to solve:

Simplifying
1 + z + z2 = 0

Solving
1 + z + z2 = 0

Begin completing the square.

Move the constant term to the right:

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

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

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

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

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

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

Combine like terms: -1 + 0.25 = -0.75
0.25 + z + z2 = -0.75

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

Can't calculate square root of the right side.
