Solution for 1.5w(180-3w)=180 equation:


Simplifying
1.5w(180 + -3w) = 180
(180 * 1.5w + -3w * 1.5w) = 180
(270w + -4.5w2) = 180

Solving
270w + -4.5w2 = 180

Solving for variable 'w'.

Reorder the terms:
-180 + 270w + -4.5w2 = 180 + -180

Combine like terms: 180 + -180 = 0
-180 + 270w + -4.5w2 = 0

Begin completing the square.  Divide all terms by
-4.5 the coefficient of the squared term: 

Divide each side by '-4.5'.
40 + -60w + w2 = 0

Move the constant term to the right:

Add '-40' to each side of the equation.
40 + -60w + -40 + w2 = 0 + -40

Reorder the terms:
40 + -40 + -60w + w2 = 0 + -40

Combine like terms: 40 + -40 = 0
0 + -60w + w2 = 0 + -40
-60w + w2 = 0 + -40

Combine like terms: 0 + -40 = -40
-60w + w2 = -40

The w term is -60w.  Take half its coefficient (-30).
Square it (900) and add it to both sides.

Add '900' to each side of the equation.
-60w + 900 + w2 = -40 + 900

Reorder the terms:
900 + -60w + w2 = -40 + 900

Combine like terms: -40 + 900 = 860
900 + -60w + w2 = 860

Factor a perfect square on the left side:
(w + -30)(w + -30) = 860

Calculate the square root of the right side: 29.325756597
