Solving
-14 + 3w + w2 = 0

Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '14' to each side of the equation.
-14 + 3w + 14 + w2 = 0 + 14

Reorder the terms:
-14 + 14 + 3w + w2 = 0 + 14

Combine like terms: -14 + 14 = 0
0 + 3w + w2 = 0 + 14
3w + w2 = 0 + 14

Combine like terms: 0 + 14 = 14
3w + w2 = 14

The w term is 3w.  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.
3w + 2.25 + w2 = 14 + 2.25

Reorder the terms:
2.25 + 3w + w2 = 14 + 2.25

Combine like terms: 14 + 2.25 = 16.25
2.25 + 3w + w2 = 16.25

Factor a perfect square on the left side:
(w + 1.5)(w + 1.5) = 16.25
