Solve x + 11 = 0.

Answer: x = - 11

a negative 11 negates a positive 11 and brings you to 0

The answer is Simplifying

x (x + 11) = 0

Reorder the terms:

x (11 + x) = 0

(11 * x + x * x) = 0

(11x + x2) = 0

Solving

11x + x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), 'x'.

x (11 + x) = 0

Set the factor 'x' equal to zero and attempt to solve:

Simplifying

x = 0

Solving

x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying

x = 0

Set the factor ' (11 + x) ' equal to zero and attempt to solve:

Simplifying

11 + x = 0

Solving

11 + x = 0

Move all terms containing x to the left, all other terms to the right.

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

11 + - 11 + x = 0 + - 11

Combine like terms: 11 + - 11 = 0

0 + x = 0 + - 11

x = 0 + - 11

Combine like terms: 0 + - 11 = - 11

x = - 11

Simplifying

x = - 11

Solution

x = {0, - 11}
