Solution for 5w^2=8w-12 equation:


Simplifying
5w2 = 8w + -12

Reorder the terms:
5w2 = -12 + 8w

Solving
5w2 = -12 + 8w

Solving for variable 'w'.

Reorder the terms:
12 + -8w + 5w2 = -12 + 8w + 12 + -8w

Reorder the terms:
12 + -8w + 5w2 = -12 + 12 + 8w + -8w

Combine like terms: -12 + 12 = 0
12 + -8w + 5w2 = 0 + 8w + -8w
12 + -8w + 5w2 = 8w + -8w

Combine like terms: 8w + -8w = 0
12 + -8w + 5w2 = 0

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

Divide each side by '5'.
2.4 + -1.6w + w2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + -1.6w + -2.4 + w2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + -1.6w + w2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + -1.6w + w2 = 0 + -2.4
-1.6w + w2 = 0 + -2.4

Combine like terms: 0 + -2.4 = -2.4
-1.6w + w2 = -2.4

The w term is -1.6w.  Take half its coefficient (-0.8).
Square it (0.64) and add it to both sides.

Add '0.64' to each side of the equation.
-1.6w + 0.64 + w2 = -2.4 + 0.64

Reorder the terms:
0.64 + -1.6w + w2 = -2.4 + 0.64

Combine like terms: -2.4 + 0.64 = -1.76
0.64 + -1.6w + w2 = -1.76

Factor a perfect square on the left side:
(w + -0.8)(w + -0.8) = -1.76

Can't calculate square root of the right side.

The solution to this equation could not be determined.
