Solution for x^2+x=-22 equation:

Simplifying
x2 + x = -22

Reorder the terms:
x + x2 = -22

Solving
x + x2 = -22

Solving for variable 'x'.

Reorder the terms:
22 + x + x2 = -22 + 22

Combine like terms: -22 + 22 = 0
22 + x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-22' to each side of the equation.
22 + x + -22 + x2 = 0 + -22

Reorder the terms:
22 + -22 + x + x2 = 0 + -22

Combine like terms: 22 + -22 = 0
0 + x + x2 = 0 + -22
x + x2 = 0 + -22

Combine like terms: 0 + -22 = -22
x + x2 = -22

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.
x + 0.25 + x2 = -22 + 0.25

Reorder the terms:
0.25 + x + x2 = -22 + 0.25

Combine like terms: -22 + 0.25 = -21.75
0.25 + x + x2 = -21.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -21.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
