Solution for w(w-4)-3w(3w-2)=(w-4) equation:


Simplifying
w(w + -4) + -3w(3w + -2) = (w + -4)

Reorder the terms:
w(-4 + w) + -3w(3w + -2) = (w + -4)
(-4 * w + w * w) + -3w(3w + -2) = (w + -4)
(-4w + w2) + -3w(3w + -2) = (w + -4)

Reorder the terms:
-4w + w2 + -3w(-2 + 3w) = (w + -4)
-4w + w2 + (-2 * -3w + 3w * -3w) = (w + -4)
-4w + w2 + (6w + -9w2) = (w + -4)

Reorder the terms:
-4w + 6w + w2 + -9w2 = (w + -4)

Combine like terms: -4w + 6w = 2w
2w + w2 + -9w2 = (w + -4)

Combine like terms: w2 + -9w2 = -8w2
2w + -8w2 = (w + -4)

Reorder the terms:
2w + -8w2 = (-4 + w)

Remove parenthesis around (-4 + w)
2w + -8w2 = -4 + w

Solving
2w + -8w2 = -4 + w

Solving for variable 'w'.

Reorder the terms:
4 + 2w + -1w + -8w2 = -4 + w + 4 + -1w

Combine like terms: 2w + -1w = 1w
4 + 1w + -8w2 = -4 + w + 4 + -1w

Reorder the terms:
4 + 1w + -8w2 = -4 + 4 + w + -1w

Combine like terms: -4 + 4 = 0
4 + 1w + -8w2 = 0 + w + -1w
4 + 1w + -8w2 = w + -1w

Combine like terms: w + -1w = 0
4 + 1w + -8w2 = 0

Begin completing the square.  Divide all terms by
-8 the coefficient of the squared term: 

Divide each side by '-8'.
-0.5 + -0.125w + w2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + -0.125w + 0.5 + w2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + -0.125w + w2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + -0.125w + w2 = 0 + 0.5
-0.125w + w2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
-0.125w + w2 = 0.5

The w term is -0.125w.  Take half its coefficient (-0.0625).
Square it (0.00390625) and add it to both sides.

Add '0.00390625' to each side of the equation.
-0.125w + 0.00390625 + w2 = 0.5 + 0.00390625

Reorder the terms:
0.00390625 + -0.125w + w2 = 0.5 + 0.00390625

Combine like terms: 0.5 + 0.00390625 = 0.50390625
0.00390625 + -0.125w + w2 = 0.50390625

Factor a perfect square on the left side:
(w + -0.0625)(w + -0.0625) = 0.50390625

Calculate the square root of the right side: 0.709863543
