Solution for -2w^2+1w-45=0 equation:


Simplifying
-2w2 + 1w + -45 = 0

Reorder the terms:
-45 + 1w + -2w2 = 0

Solving
-45 + 1w + -2w2 = 0

Solving for variable 'w'.

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

Divide each side by '-2'.
22.5 + -0.5w + w2 = 0

Move the constant term to the right:

Add '-22.5' to each side of the equation.
22.5 + -0.5w + -22.5 + w2 = 0 + -22.5

Reorder the terms:
22.5 + -22.5 + -0.5w + w2 = 0 + -22.5

Combine like terms: 22.5 + -22.5 = 0.0
0.0 + -0.5w + w2 = 0 + -22.5
-0.5w + w2 = 0 + -22.5

Combine like terms: 0 + -22.5 = -22.5
-0.5w + w2 = -22.5

The w term is -0.5w.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5w + 0.0625 + w2 = -22.5 + 0.0625

Reorder the terms:
0.0625 + -0.5w + w2 = -22.5 + 0.0625

Combine like terms: -22.5 + 0.0625 = -22.4375
0.0625 + -0.5w + w2 = -22.4375

Factor a perfect square on the left side:
(w + -0.25)(w + -0.25) = -22.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
