x(3 + x)(6 + x) = 70

Multiply (3 + x) * (6 + x)
x(3(6 + x) + x(6 + x)) = 70
x((6 * 3 + x * 3) + x(6 + x)) = 70
x((18 + 3x) + x(6 + x)) = 70
x(18 + 3x + (6 * x + x * x)) = 70
x(18 + 3x + (6x + x2)) = 70

Combine like terms: 3x + 6x = 9x
x(18 + 9x + x2) = 70
(18 * x + 9x * x + x2 * x) = 70
(18x + 9x2 + x3) = 70

Solving
18x + 9x2 + x3 = 70

Solving for variable 'x'.
