5x^2+x+6=0

Solution for 5x^2+x+6=0 equation:

Simplifying
5x2 + x + 6 = 0

Reorder the terms:
6 + x + 5x2 = 0

Solving
6 + x + 5x2 = 0

Solving for variable 'x'.

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

Divide each side by '5'.
1.2 + 0.2x + x2 = 0

Move the constant term to the right:

Add '-1.2' to each side of the equation.
1.2 + 0.2x + -1.2 + x2 = 0 + -1.2

Reorder the terms:
1.2 + -1.2 + 0.2x + x2 = 0 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + 0.2x + x2 = 0 + -1.2
0.2x + x2 = 0 + -1.2

Combine like terms: 0 + -1.2 = -1.2
0.2x + x2 = -1.2

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.
0.2x + 0.25 + x2 = -1.2 + 0.25

Reorder the terms:
0.25 + 0.2x + x2 = -1.2 + 0.25

Combine like terms: -1.2 + 0.25 = -0.95
0.25 + 0.2x + x2 = -0.95

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -0.95

Can't calculate square root of the right side.

The solution to this equation could not be determined.
