2w2 = 4w + -35

Reorder the terms:
2w2 = -35 + 4w

Solving
2w2 = -35 + 4w

Solving for variable 'w'.

Reorder the terms:
35 + -4w + 2w2 = -35 + 4w + 35 + -4w

Reorder the terms:
35 + -4w + 2w2 = -35 + 35 + 4w + -4w

Combine like terms: -35 + 35 = 0
35 + -4w + 2w2 = 0 + 4w + -4w
35 + -4w + 2w2 = 4w + -4w

Combine like terms: 4w + -4w = 0
35 + -4w + 2w2 = 0

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

Divide each side by '2'.
17.5 + -2w + w2 = 0

Move the constant term to the right:

Add '-17.5' to each side of the equation.
17.5 + -2w + -17.5 + w2 = 0 + -17.5

Reorder the terms:
17.5 + -17.5 + -2w + w2 = 0 + -17.5

Combine like terms: 17.5 + -17.5 = 0.0
0.0 + -2w + w2 = 0 + -17.5
-2w + w2 = 0 + -17.5

Combine like terms: 0 + -17.5 = -17.5
-2w + w2 = -17.5

The w term is -2w.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2w + 1 + w2 = -17.5 + 1

Reorder the terms:
1 + -2w + w2 = -17.5 + 1

Combine like terms: -17.5 + 1 = -16.5
1 + -2w + w2 = -16.5

Factor a perfect square on the left side:
(w + -1)(w + -1) = -16.5

Can't calculate square root of the right side.

The solution to this equation could not be determined.
