Solution for w^2=(w-8) equation:


Simplifying
w2 = (w + -8)

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

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

Solving
w2 = -8 + w

Solving for variable 'w'.

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

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

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

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

Begin completing the square.

Move the constant term to the right:

Add '-8' to each side of the equation.
8 + -1w + -8 + w2 = 0 + -8

Reorder the terms:
8 + -8 + -1w + w2 = 0 + -8

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

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

The w term is -1w.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1w + 0.25 + w2 = -8 + 0.25

Reorder the terms:
0.25 + -1w + w2 = -8 + 0.25

Combine like terms: -8 + 0.25 = -7.75
0.25 + -1w + w2 = -7.75

Factor a perfect square on the left side:
(w + -0.5)(w + -0.5) = -7.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
