(x+8)x(x+9)=

Solution for (x+8)x(x+9)= equation:

Simplifying
(x + 8) * x(x + 9) = 0

Reorder the terms:
(8 + x) * x(x + 9) = 0

Reorder the terms:
(8 + x) * x(9 + x) = 0

Reorder the terms for easier multiplication:
x(8 + x)(9 + x) = 0

Multiply (8 + x) * (9 + x)
x(8(9 + x) + x(9 + x)) = 0
x((9 * 8 + x * 8) + x(9 + x)) = 0
x((72 + 8x) + x(9 + x)) = 0
x(72 + 8x + (9 * x + x * x)) = 0
x(72 + 8x + (9x + x2)) = 0

Combine like terms: 8x + 9x = 17x
x(72 + 17x + x2) = 0
(72 * x + 17x * x + x2 * x) = 0
(72x + 17x2 + x3) = 0

Solving
72x + 17x2 + x3 = 0
