144=x(x+2)*6

Solution for 144=x(x+2)*6 equation:

Simplifying
144 = x(x + 2) * 6

Reorder the terms:
144 = x(2 + x) * 6

Reorder the terms for easier multiplication:
144 = 6x(2 + x)
144 = (2 * 6x + x * 6x)
144 = (12x + 6x2)

Solving
144 = 12x + 6x2

Solving for variable 'x'.

Reorder the terms:
144 + -12x + -6x2 = 12x + -12x + 6x2 + -6x2

Combine like terms: 12x + -12x = 0
144 + -12x + -6x2 = 0 + 6x2 + -6x2
144 + -12x + -6x2 = 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
144 + -12x + -6x2 = 0

Factor out the Greatest Common Factor (GCF), '6'.
6(24 + -2x + -1x2) = 0

Factor a trinomial.

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

Simplifying
4 + -1x = 0

Solving
4 + -1x = 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 + -1x = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -1x = 0 + -4
-1x = 0 + -4

Combine like terms: 0 + -4 = -4
-1x = -4

Divide each side by '-1'.
x = 4

Simplifying
x = 4
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 = {4, -6}
