Solution for 1*x^3+1*x^2+1*x=0 equation:

Simplifying
1x3 + 1x2 + 1x = 0

Reorder the terms:
1x + 1x2 + 1x3 = 0

Solving
1x + 1x2 + 1x3 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), 'x'.
x(1 + x + x2) = 0

Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

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

Simplifying
x = 0
Subproblem 2
Set the factor '(1 + x + x2)' equal to zero and attempt to solve:

Simplifying
1 + x + x2 = 0

Solving
1 + x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + x + -1 + x2 = 0 + -1

Reorder the terms:
1 + -1 + x + x2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + x + x2 = 0 + -1
x + x2 = 0 + -1

Combine like terms: 0 + -1 = -1
x + x2 = -1

The x term is x.  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.
x + 0.25 + x2 = -1 + 0.25

Reorder the terms:
0.25 + x + x2 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + x + x2 = -0.75

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

Can't calculate square root of the right side.
