Solution for w^2=9(w-3) equation:


Simplifying
w2 = 9(w + -3)

Reorder the terms:
w2 = 9(-3 + w)
w2 = (-3 * 9 + w * 9)
w2 = (-27 + 9w)

Solving
w2 = -27 + 9w

Solving for variable 'w'.

Reorder the terms:
27 + -9w + w2 = -27 + 9w + 27 + -9w

Reorder the terms:
27 + -9w + w2 = -27 + 27 + 9w + -9w

Combine like terms: -27 + 27 = 0
27 + -9w + w2 = 0 + 9w + -9w
27 + -9w + w2 = 9w + -9w

Combine like terms: 9w + -9w = 0
27 + -9w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-27' to each side of the equation.
27 + -9w + -27 + w2 = 0 + -27

Reorder the terms:
27 + -27 + -9w + w2 = 0 + -27

Combine like terms: 27 + -27 = 0
0 + -9w + w2 = 0 + -27
-9w + w2 = 0 + -27

Combine like terms: 0 + -27 = -27
-9w + w2 = -27

The w term is -9w.  Take half its coefficient (-4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
-9w + 20.25 + w2 = -27 + 20.25

Reorder the terms:
20.25 + -9w + w2 = -27 + 20.25

Combine like terms: -27 + 20.25 = -6.75
20.25 + -9w + w2 = -6.75

Factor a perfect square on the left side:
(w + -4.5)(w + -4.5) = -6.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
