(x+3)(x+4)(2)=0

Solution for (x+3)(x+4)(2)=0 equation:

Simplifying
(x + 3)(x + 4)(2) = 0

Reorder the terms:
(3 + x)(x + 4)(2) = 0

Reorder the terms:
(3 + x)(4 + x)(2) = 0

Reorder the terms for easier multiplication:
2(3 + x)(4 + x) = 0

Multiply (3 + x) * (4 + x)
2(3(4 + x) + x(4 + x)) = 0
2((4 * 3 + x * 3) + x(4 + x)) = 0
2((12 + 3x) + x(4 + x)) = 0
2(12 + 3x + (4 * x + x * x)) = 0
2(12 + 3x + (4x + x2)) = 0

Combine like terms: 3x + 4x = 7x
2(12 + 7x + x2) = 0
(12 * 2 + 7x * 2 + x2 * 2) = 0
(24 + 14x + 2x2) = 0

Solving
24 + 14x + 2x2 = 0

Subproblem 1
Set the factor '(4 + x)' equal to zero and attempt to solve:

Simplifying
4 + x = 0

Solving
4 + x = 0

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

Add '-4' to each side of the equation.
4 + -4 + x = 0 + -4

Combine like terms: 4 + -4 = 0
0 + x = 0 + -4
x = 0 + -4

Combine like terms: 0 + -4 = -4
x = -4

Simplifying
x = -4
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 = {-4, -3}
