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
