Solution for w^2=7(w-2) equation:


Simplifying
w2 = 7(w + -2)

Reorder the terms:
w2 = 7(-2 + w)
w2 = (-2 * 7 + w * 7)
w2 = (-14 + 7w)

Solving
w2 = -14 + 7w

Solving for variable 'w'.

Reorder the terms:
14 + -7w + w2 = -14 + 7w + 14 + -7w

Reorder the terms:
14 + -7w + w2 = -14 + 14 + 7w + -7w

Combine like terms: -14 + 14 = 0
14 + -7w + w2 = 0 + 7w + -7w
14 + -7w + w2 = 7w + -7w

Combine like terms: 7w + -7w = 0
14 + -7w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-14' to each side of the equation.
14 + -7w + -14 + w2 = 0 + -14

Reorder the terms:
14 + -14 + -7w + w2 = 0 + -14

Combine like terms: 14 + -14 = 0
0 + -7w + w2 = 0 + -14
-7w + w2 = 0 + -14

Combine like terms: 0 + -14 = -14
-7w + w2 = -14

The w term is -7w.  Take half its coefficient (-3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
-7w + 12.25 + w2 = -14 + 12.25

Reorder the terms:
12.25 + -7w + w2 = -14 + 12.25

Combine like terms: -14 + 12.25 = -1.75
12.25 + -7w + w2 = -1.75

Factor a perfect square on the left side:
(w + -3.5)(w + -3.5) = -1.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
