25 + 12w + 4w2 = 0

Solving for variable 'w'.

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

Divide each side by '4'.
6.25 + 3w + w2 = 0

Move the constant term to the right:

Add '-6.25' to each side of the equation.
6.25 + 3w + -6.25 + w2 = 0 + -6.25

Reorder the terms:
6.25 + -6.25 + 3w + w2 = 0 + -6.25

Combine like terms: 6.25 + -6.25 = 0.00
0.00 + 3w + w2 = 0 + -6.25
3w + w2 = 0 + -6.25

Combine like terms: 0 + -6.25 = -6.25
3w + w2 = -6.25

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 = -6.25 + 2.25

Reorder the terms:
2.25 + 3w + w2 = -6.25 + 2.25

Combine like terms: -6.25 + 2.25 = -4
2.25 + 3w + w2 = -4

Factor a perfect square on the left side:
(w + 1.5)(w + 1.5) = -4

Can't calculate square root of the right side.

The solution to this equation could not be determined.
