Solution for x=(x-9)*x equation:


Simplifying
x = (x + -9) * x

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

Reorder the terms for easier multiplication:
x = x(-9 + x)
x = (-9 * x + x * x)
x = (-9x + x2)

Solving
x = -9x + x2

Solving for variable 'x'.

Combine like terms: x + 9x = 10x
10x + -1x2 = -9x + x2 + 9x + -1x2

Reorder the terms:
10x + -1x2 = -9x + 9x + x2 + -1x2

Combine like terms: -9x + 9x = 0
10x + -1x2 = 0 + x2 + -1x2
10x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
10x + -1x2 = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(10 + -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 '(10 + -1x)' equal to zero and attempt to solve: Simplifying 10 + -1x = 0 Solving 10 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -1x = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -1x = 0 + -10 -1x = 0 + -10 Combine like terms: 0 + -10 = -10 -1x = -10 Divide each side by '-1'. x = 10 Simplifying x = 10

Solution

x = {0, 10}
