Solving
81 + 9x2 + x4 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-81' to each side of the equation.
81 + 9x2 + -81 + x4 = 0 + -81

Reorder the terms:
81 + -81 + 9x2 + x4 = 0 + -81

Combine like terms: 81 + -81 = 0
0 + 9x2 + x4 = 0 + -81
9x2 + x4 = 0 + -81

Combine like terms: 0 + -81 = -81
9x2 + x4 = -81

The x term is 9x2.  Take half its coefficient (4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
9x2 + 20.25 + x4 = -81 + 20.25

Reorder the terms:
20.25 + 9x2 + x4 = -81 + 20.25

Combine like terms: -81 + 20.25 = -60.75
20.25 + 9x2 + x4 = -60.75

Factor a perfect square on the left side:
(x2 + 4.5)(x2 + 4.5) = -60.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
