(x+8)(x+3)=

Solution for (x+8)(x+3)= equation:

Simplifying
(x + 8)(x + 3) = 0

Reorder the terms:
(8 + x)(x + 3) = 0

Reorder the terms:
(8 + x)(3 + x) = 0

Multiply (8 + x) * (3 + x)
(8(3 + x) + x(3 + x)) = 0
((3 * 8 + x * 8) + x(3 + x)) = 0
((24 + 8x) + x(3 + x)) = 0
(24 + 8x + (3 * x + x * x)) = 0
(24 + 8x + (3x + x2)) = 0

Combine like terms: 8x + 3x = 11x
(24 + 11x + x2) = 0

Solving
24 + 11x + x2 = 0

Subproblem 1
Set the factor '(8 + x)' equal to zero and attempt to solve:

Simplifying
8 + x = 0

Solving
8 + x = 0

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

Add '-8' to each side of the equation.
8 + -8 + x = 0 + -8

Combine like terms: 8 + -8 = 0
0 + x = 0 + -8
x = 0 + -8

Combine like terms: 0 + -8 = -8
x = -8

Simplifying
x = -8
Subproblem 2
Set the factor '(3 + x)' equal to zero and attempt to solve:

Simplifying
3 + x = 0

Solving
3 + x = 0

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

Add '-3' to each side of the equation.
3 + -3 + x = 0 + -3

Combine like terms: 3 + -3 = 0
0 + x = 0 + -3
x = 0 + -3

Combine like terms: 0 + -3 = -3
x = -3

Simplifying
x = -3
Solution
x = {-8, -3}
