Solution for w^2-3w+180=0 equation:


Simplifying
w2 + -3w + 180 = 0

Reorder the terms:
180 + -3w + w2 = 0

Solving
180 + -3w + w2 = 0

Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '-180' to each side of the equation.
180 + -3w + -180 + w2 = 0 + -180

Reorder the terms:
180 + -180 + -3w + w2 = 0 + -180

Combine like terms: 180 + -180 = 0
0 + -3w + w2 = 0 + -180
-3w + w2 = 0 + -180

Combine like terms: 0 + -180 = -180
-3w + w2 = -180

The w term is -3w.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3w + 2.25 + w2 = -180 + 2.25

Reorder the terms:
2.25 + -3w + w2 = -180 + 2.25

Combine like terms: -180 + 2.25 = -177.75
2.25 + -3w + w2 = -177.75

Factor a perfect square on the left side:
(w + -1.5)(w + -1.5) = -177.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
