Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-14' to each side of the equation.
14 + 3x + -14 + x2 = 0 + -14

Reorder the terms:
14 + -14 + 3x + x2 = 0 + -14

Combine like terms: 14 + -14 = 0
0 + 3x + x2 = 0 + -14
3x + x2 = 0 + -14

Combine like terms: 0 + -14 = -14
3x + x2 = -14

The x term is 3x.  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.
3x + 2.25 + x2 = -14 + 2.25

Reorder the terms:
2.25 + 3x + x2 = -14 + 2.25

Combine like terms: -14 + 2.25 = -11.75
2.25 + 3x + x2 = -11.75

Factor a perfect square on the left side:
(x + 1.5)(x + 1.5) = -11.75

Can't calculate square root of the right side.
