77 + 3w + 2w2 = 0

Solving for variable 'w'.

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

Divide each side by '2'.
38.5 + 1.5w + w2 = 0

Move the constant term to the right:

Add '-38.5' to each side of the equation.
38.5 + 1.5w + -38.5 + w2 = 0 + -38.5

Reorder the terms:
38.5 + -38.5 + 1.5w + w2 = 0 + -38.5

Combine like terms: 38.5 + -38.5 = 0.0
0.0 + 1.5w + w2 = 0 + -38.5
1.5w + w2 = 0 + -38.5

Combine like terms: 0 + -38.5 = -38.5
1.5w + w2 = -38.5

The w term is 1.5w.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5w + 0.5625 + w2 = -38.5 + 0.5625

Reorder the terms:
0.5625 + 1.5w + w2 = -38.5 + 0.5625

Combine like terms: -38.5 + 0.5625 = -37.9375
0.5625 + 1.5w + w2 = -37.9375

Factor a perfect square on the left side:
(w + 0.75)(w + 0.75) = -37.9375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
