Solving for variable 'x'.

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

Divide each side by '5'.
1.2 + 3x2 + x4 = 0

Move the constant term to the right:

Add '-1.2' to each side of the equation.
1.2 + 3x2 + -1.2 + x4 = 0 + -1.2

Reorder the terms:
1.2 + -1.2 + 3x2 + x4 = 0 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + 3x2 + x4 = 0 + -1.2
3x2 + x4 = 0 + -1.2

Combine like terms: 0 + -1.2 = -1.2
3x2 + x4 = -1.2

The x term is 3x2.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3x2 + 2.25 + x4 = -1.2 + 2.25

Reorder the terms:
2.25 + 3x2 + x4 = -1.2 + 2.25
