X(x+1)(x+3)=72

Solution for X(x+1)(x+3)=72 equation:

Simplifying
X(x + 1)(x + 3) = 72

Reorder the terms:
X(1 + x)(x + 3) = 72

Reorder the terms:
X(1 + x)(3 + x) = 72

Multiply (1 + x) * (3 + x)
X(1(3 + x) + x(3 + x)) = 72
X((3 * 1 + x * 1) + x(3 + x)) = 72
X((3 + 1x) + x(3 + x)) = 72
X(3 + 1x + (3 * x + x * x)) = 72
X(3 + 1x + (3x + x2)) = 72

Combine like terms: 1x + 3x = 4x
X(3 + 4x + x2) = 72
(3 * X + 4x * X + x2 * X) = 72
(3X + 4xX + x2X) = 72

Solving
3X + 4xX + x2X = 72

Solving for variable 'X'.
