Solution for (x)(x-3)(x+3)=0 equation:


Simplifying
(x)(x + -3)(x + 3) = 0

Reorder the terms:
x(-3 + x)(x + 3) = 0

Reorder the terms:
x(-3 + x)(3 + x) = 0

Multiply (-3 + x) * (3 + x)
x(-3(3 + x) + x(3 + x)) = 0
x((3 * -3 + x * -3) + x(3 + x)) = 0
x((-9 + -3x) + x(3 + x)) = 0
x(-9 + -3x + (3 * x + x * x)) = 0
x(-9 + -3x + (3x + x2)) = 0

Combine like terms: -3x + 3x = 0
x(-9 + 0 + x2) = 0
x(-9 + x2) = 0
(-9 * x + x2 * x) = 0
(-9x + x3) = 0
