Solution for x(2x+1)(3x+9)=0 equation:


Simplifying
x(2x + 1)(3x + 9) = 0

Reorder the terms:
x(1 + 2x)(3x + 9) = 0

Reorder the terms:
x(1 + 2x)(9 + 3x) = 0

Multiply (1 + 2x) * (9 + 3x)
x(1(9 + 3x) + 2x * (9 + 3x)) = 0
x((9 * 1 + 3x * 1) + 2x * (9 + 3x)) = 0
x((9 + 3x) + 2x * (9 + 3x)) = 0
x(9 + 3x + (9 * 2x + 3x * 2x)) = 0
x(9 + 3x + (18x + 6x2)) = 0

Combine like terms: 3x + 18x = 21x
x(9 + 21x + 6x2) = 0
(9 * x + 21x * x + 6x2 * x) = 0
(9x + 21x2 + 6x3) = 0

Solving
9x + 21x2 + 6x3 = 0
