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


Simplifying
(x + 3)(x + 0)(x + -9) = 0

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

Reorder the terms:
(3 + x)(0 + x)(x + -9) = 0
Remove the zero:
(3 + x)(x)(x + -9) = 0

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

Reorder the terms for easier multiplication:
x(3 + x)(-9 + x) = 0

Multiply (3 + x) * (-9 + x)
x(3(-9 + x) + x(-9 + x)) = 0
x((-9 * 3 + x * 3) + x(-9 + x)) = 0
x((-27 + 3x) + x(-9 + x)) = 0
x(-27 + 3x + (-9 * x + x * x)) = 0
x(-27 + 3x + (-9x + x2)) = 0

Combine like terms: 3x + -9x = -6x
x(-27 + -6x + x2) = 0
(-27 * x + -6x * x + x2 * x) = 0
(-27x + -6x2 + x3) = 0

Solving
-27x + -6x2 + x3 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), 'x'.
x(-27 + -6x + x2) = 0

Factor a trinomial.
x((-3 + -1x)(9 + -1x)) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-3 + -1x)' equal to zero and attempt to solve: Simplifying -3 + -1x = 0 Solving -3 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + -1x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1x = 0 + 3 -1x = 0 + 3 Combine like terms: 0 + 3 = 3 -1x = 3 Divide each side by '-1'. x = -3 Simplifying x = -3

Subproblem 3

Set the factor '(9 + -1x)' equal to zero and attempt to solve: Simplifying 9 + -1x = 0 Solving 9 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = 0 + -9 -1x = 0 + -9 Combine like terms: 0 + -9 = -9 -1x = -9 Divide each side by '-1'. x = 9 Simplifying x = 9

Solution

x = {0, -3, 9}
