Solving for variable 'w'.

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

Divide each side by '4'.
-1 + -2.25w + w2 = 0

Move the constant term to the right:

Add '1' to each side of the equation.
-1 + -2.25w + 1 + w2 = 0 + 1

Reorder the terms:
-1 + 1 + -2.25w + w2 = 0 + 1

Combine like terms: -1 + 1 = 0
0 + -2.25w + w2 = 0 + 1
-2.25w + w2 = 0 + 1

Combine like terms: 0 + 1 = 1
-2.25w + w2 = 1

The w term is -2.25w.  Take half its coefficient (-1.125).
Square it (1.265625) and add it to both sides.

Add '1.265625' to each side of the equation.
-2.25w + 1.265625 + w2 = 1 + 1.265625

Reorder the terms:
1.265625 + -2.25w + w2 = 1 + 1.265625
