Solution for 2w^2=3w-8 equation:


Simplifying
2w2 = 3w + -8

Reorder the terms:
2w2 = -8 + 3w

Solving
2w2 = -8 + 3w

Solving for variable 'w'.

Reorder the terms:
8 + -3w + 2w2 = -8 + 3w + 8 + -3w

Reorder the terms:
8 + -3w + 2w2 = -8 + 8 + 3w + -3w

Combine like terms: -8 + 8 = 0
8 + -3w + 2w2 = 0 + 3w + -3w
8 + -3w + 2w2 = 3w + -3w

Combine like terms: 3w + -3w = 0
8 + -3w + 2w2 = 0

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

Divide each side by '2'.
4 + -1.5w + w2 = 0

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -1.5w + -4 + w2 = 0 + -4

Reorder the terms:
4 + -4 + -1.5w + w2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -1.5w + w2 = 0 + -4
-1.5w + w2 = 0 + -4

Combine like terms: 0 + -4 = -4
-1.5w + w2 = -4

The w term is -1.5w.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5w + 0.5625 + w2 = -4 + 0.5625

Reorder the terms:
0.5625 + -1.5w + w2 = -4 + 0.5625

Combine like terms: -4 + 0.5625 = -3.4375
0.5625 + -1.5w + w2 = -3.4375

Factor a perfect square on the left side:
(w + -0.75)(w + -0.75) = -3.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
