Solution for 8w^2-8w+19=0 equation:


Simplifying
8w2 + -8w + 19 = 0

Reorder the terms:
19 + -8w + 8w2 = 0

Solving
19 + -8w + 8w2 = 0

Solving for variable 'w'.

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

Divide each side by '8'.
2.375 + -1w + w2 = 0

Move the constant term to the right:

Add '-2.375' to each side of the equation.
2.375 + -1w + -2.375 + w2 = 0 + -2.375

Reorder the terms:
2.375 + -2.375 + -1w + w2 = 0 + -2.375

Combine like terms: 2.375 + -2.375 = 0.000
0.000 + -1w + w2 = 0 + -2.375
-1w + w2 = 0 + -2.375

Combine like terms: 0 + -2.375 = -2.375
-1w + w2 = -2.375

The w term is -1w.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1w + 0.25 + w2 = -2.375 + 0.25

Reorder the terms:
0.25 + -1w + w2 = -2.375 + 0.25

Combine like terms: -2.375 + 0.25 = -2.125
0.25 + -1w + w2 = -2.125

Factor a perfect square on the left side:
(w + -0.5)(w + -0.5) = -2.125

Can't calculate square root of the right side.

The solution to this equation could not be determined.
