Solving for variable 'x'.

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

Divide each side by '4'.
-1 + 0.25x3 + x6 = 0

Move the constant term to the right:

Add '1' to each side of the equation.
-1 + 0.25x3 + 1 + x6 = 0 + 1

Reorder the terms:
-1 + 1 + 0.25x3 + x6 = 0 + 1

Combine like terms: -1 + 1 = 0
0 + 0.25x3 + x6 = 0 + 1
0.25x3 + x6 = 0 + 1

Combine like terms: 0 + 1 = 1
0.25x3 + x6 = 1

The x term is x3.  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.
0.25x3 + 0.25 + x6 = 1 + 0.25

Reorder the terms:
0.25 + 0.25x3 + x6 = 1 + 0.25

Combine like terms: 1 + 0.25 = 1.25
0.25 + 0.25x3 + x6 = 1.25

Factor a perfect square on the left side:
(x3 + 0.5)(x3 + 0.5) = 1.25

Calculate the square root of the right side: 1.118033989
