-4x^2+x-3=0

Solution for -4x^2+x-3=0 equation:

Simplifying
-4x2 + x + -3 = 0

Reorder the terms:
-3 + x + -4x2 = 0

Solving
-3 + x + -4x2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-4 the coefficient of the squared term: 

Divide each side by '-4'.
0.75 + -0.25x + x2 = 0

Move the constant term to the right:

Add '-0.75' to each side of the equation.
0.75 + -0.25x + -0.75 + x2 = 0 + -0.75

Reorder the terms:
0.75 + -0.75 + -0.25x + x2 = 0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + -0.25x + x2 = 0 + -0.75
-0.25x + x2 = 0 + -0.75

Combine like terms: 0 + -0.75 = -0.75
-0.25x + x2 = -0.75

The x term is x.  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.
-0.25x + 0.25 + x2 = -0.75 + 0.25

Reorder the terms:
0.25 + -0.25x + x2 = -0.75 + 0.25

Combine like terms: -0.75 + 0.25 = -0.5
0.25 + -0.25x + x2 = -0.5

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

Can't calculate square root of the right side.

The solution to this equation could not be determined.
