Solution for =(9-3x)(-6x) equation:


Simplifying
0 = (9 + -3x)(-6x)

Remove parenthesis around (-6x)
0 = (9 + -3x) * -6x

Reorder the terms for easier multiplication:
0 = -6x(9 + -3x)
0 = (9 * -6x + -3x * -6x)
0 = (-54x + 18x2)

Solving
0 = -54x + 18x2

Solving for variable 'x'.
Remove the zero:
54x + -18x2 = -54x + 18x2 + 54x + -18x2

Reorder the terms:
54x + -18x2 = -54x + 54x + 18x2 + -18x2

Combine like terms: -54x + 54x = 0
54x + -18x2 = 0 + 18x2 + -18x2
54x + -18x2 = 18x2 + -18x2

Combine like terms: 18x2 + -18x2 = 0
54x + -18x2 = 0

Factor out the Greatest Common Factor (GCF), '18x'.
18x(3 + -1x) = 0

Ignore the factor 18.

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

Solution

x = {0, 3}
