(12+2x)(18+2x)=

Solution for (12+2x)(18+2x)= equation:

Simplifying
(12 + 2x)(18 + 2x) = 0

Multiply (12 + 2x) * (18 + 2x)
(12(18 + 2x) + 2x * (18 + 2x)) = 0
((18 * 12 + 2x * 12) + 2x * (18 + 2x)) = 0
((216 + 24x) + 2x * (18 + 2x)) = 0
(216 + 24x + (18 * 2x + 2x * 2x)) = 0
(216 + 24x + (36x + 4x2)) = 0

Combine like terms: 24x + 36x = 60x
(216 + 60x + 4x2) = 0

Subproblem 1
Set the factor '(9 + x)' equal to zero and attempt to solve:

Simplifying
9 + x = 0

Solving
9 + x = 0

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

Add '-9' to each side of the equation.
9 + -9 + x = 0 + -9

Combine like terms: 9 + -9 = 0
0 + x = 0 + -9
x = 0 + -9

Combine like terms: 0 + -9 = -9
x = -9

Simplifying
x = -9
Subproblem 2
Set the factor '(6 + x)' equal to zero and attempt to solve:

Simplifying
6 + x = 0

Solving
6 + x = 0

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

Add '-6' to each side of the equation.
6 + -6 + x = 0 + -6

Combine like terms: 6 + -6 = 0
0 + x = 0 + -6
x = 0 + -6

Combine like terms: 0 + -6 = -6
x = -6

Simplifying
x = -6
Solution
x = {-9, -6}
