Solving for variable 'x'.

Reorder the terms:
2 + 3x + -1x + x2 + 4x2 = x + -4x2 + -1x + 4x2

Combine like terms: 3x + -1x = 2x
2 + 2x + x2 + 4x2 = x + -4x2 + -1x + 4x2

Combine like terms: x2 + 4x2 = 5x2
2 + 2x + 5x2 = x + -4x2 + -1x + 4x2

Reorder the terms:
2 + 2x + 5x2 = x + -1x + -4x2 + 4x2

Combine like terms: x + -1x = 0
2 + 2x + 5x2 = 0 + -4x2 + 4x2
2 + 2x + 5x2 = -4x2 + 4x2

Combine like terms: -4x2 + 4x2 = 0
2 + 2x + 5x2 = 0

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

Divide each side by '5'.
0.4 + 0.4x + x2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + 0.4x + -0.4 + x2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + 0.4x + x2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + 0.4x + x2 = 0 + -0.4
0.4x + x2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
0.4x + x2 = -0.4

The x term is 0.4x.  Take half its coefficient (0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
0.4x + 0.04 + x2 = -0.4 + 0.04

Reorder the terms:
0.04 + 0.4x + x2 = -0.4 + 0.04

Combine like terms: -0.4 + 0.04 = -0.36
0.04 + 0.4x + x2 = -0.36

Factor a perfect square on the left side:
(x + 0.2)(x + 0.2) = -0.36

Can't calculate square root of the right side.

The solution to this equation could not be determined.
