(x+3)(x^2-6x)=0

Solution for (x+3)(x^2-6x)=0 equation:

Simplifying
(x + 3)(x2 + -6x) = 0

Reorder the terms:
(3 + x)(x2 + -6x) = 0

Reorder the terms:
(3 + x)(-6x + x2) = 0

Multiply (3 + x) * (-6x + x2)
(3(-6x + x2) + x(-6x + x2)) = 0
((-6x * 3 + x2 * 3) + x(-6x + x2)) = 0
((-18x + 3x2) + x(-6x + x2)) = 0
(-18x + 3x2 + (-6x * x + x2 * x)) = 0
(-18x + 3x2 + (-6x2 + x3)) = 0

Combine like terms: 3x2 + -6x2 = -3x2
(-18x + -3x2 + x3) = 0

Solving
-18x + -3x2 + x3 = 0
