(x+11)(x-5)=0

Solution for (x+11)(x-5)=0 equation:

Simplifying
(x + 11)(x + -5) = 0

Reorder the terms:
(11 + x)(x + -5) = 0

Reorder the terms:
(11 + x)(-5 + x) = 0

Multiply (11 + x) * (-5 + x)
(11(-5 + x) + x(-5 + x)) = 0
((-5 * 11 + x * 11) + x(-5 + x)) = 0
((-55 + 11x) + x(-5 + x)) = 0
(-55 + 11x + (-5 * x + x * x)) = 0
(-55 + 11x + (-5x + x2)) = 0

Combine like terms: 11x + -5x = 6x
(-55 + 6x + x2) = 0

Solving
-55 + 6x + x2 = 0

Solving for variable 'x'.
