Solution for w^2=9(w-5) equation:


Simplifying
w2 = 9(w + -5)

Reorder the terms:
w2 = 9(-5 + w)
w2 = (-5 * 9 + w * 9)
w2 = (-45 + 9w)

Solving
w2 = -45 + 9w

Solving for variable 'w'.

Reorder the terms:
45 + -9w + w2 = -45 + 9w + 45 + -9w

Reorder the terms:
45 + -9w + w2 = -45 + 45 + 9w + -9w

Combine like terms: -45 + 45 = 0
45 + -9w + w2 = 0 + 9w + -9w
45 + -9w + w2 = 9w + -9w

Combine like terms: 9w + -9w = 0
45 + -9w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-45' to each side of the equation.
45 + -9w + -45 + w2 = 0 + -45

Reorder the terms:
45 + -45 + -9w + w2 = 0 + -45

Combine like terms: 45 + -45 = 0
0 + -9w + w2 = 0 + -45
-9w + w2 = 0 + -45

Combine like terms: 0 + -45 = -45
-9w + w2 = -45

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 = -45 + 20.25

Reorder the terms:
20.25 + -9w + w2 = -45 + 20.25

Combine like terms: -45 + 20.25 = -24.75
20.25 + -9w + w2 = -24.75

Factor a perfect square on the left side:
(w + -4.5)(w + -4.5) = -24.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
