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


Simplifying
w2 = 4(w + -2)

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

Solving
w2 = -8 + 4w

Solving for variable 'w'.

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

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

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

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

Begin completing the square.

Move the constant term to the right:

Add '-8' to each side of the equation.
8 + -4w + -8 + w2 = 0 + -8

Reorder the terms:
8 + -8 + -4w + w2 = 0 + -8

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

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

The w term is -4w.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4w + 4 + w2 = -8 + 4

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

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

Factor a perfect square on the left side:
(w + -2)(w + -2) = -4

Can't calculate square root of the right side.

The solution to this equation could not be determined.
