-346 + -3w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '346' to each side of the equation.
-346 + -3w + 346 + w2 = 0 + 346

Reorder the terms:
-346 + 346 + -3w + w2 = 0 + 346

Combine like terms: -346 + 346 = 0
0 + -3w + w2 = 0 + 346
-3w + w2 = 0 + 346

Combine like terms: 0 + 346 = 346
-3w + w2 = 346

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 = 346 + 2.25

Reorder the terms:
2.25 + -3w + w2 = 346 + 2.25

Combine like terms: 346 + 2.25 = 348.25
2.25 + -3w + w2 = 348.25
