Step-by-step explanation:

Simplifying

x2 + 2x + 11 = 0

Reorder the terms:

11 + 2x + x2 = 0

Solving

11 + 2x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-11' to each side of the equation.

11 + 2x + -11 + x2 = 0 + -11

Reorder the terms:

11 + -11 + 2x + x2 = 0 + -11

Combine like terms: 11 + -11 = 0

0 + 2x + x2 = 0 + -11

2x + x2 = 0 + -11

Combine like terms: 0 + -11 = -11

2x + x2 = -11

The x term is 2x. Take half its coefficient (1).

Square it (1) and add it to both sides.

Add '1' to each side of the equation.

2x + 1 + x2 = -11 + 1

Reorder the terms:

1 + 2x + x2 = -11 + 1

Combine like terms: -11 + 1 = -10

1 + 2x + x2 = -10

Factor a perfect square on the left side:

(x + 1)(x + 1) = -10

Can't calculate square root of the right side.

The solution to this equation could not be determined.
