Solution for 0=X(X-2) equation:


Simplifying
0 = X(X + -2)

Reorder the terms:
0 = X(-2 + X)
0 = (-2 * X + X * X)
0 = (-2X + X2)

Solving
0 = -2X + X2

Solving for variable 'X'.
Remove the zero:
2X + -1X2 = -2X + X2 + 2X + -1X2

Reorder the terms:
2X + -1X2 = -2X + 2X + X2 + -1X2

Combine like terms: -2X + 2X = 0
2X + -1X2 = 0 + X2 + -1X2
2X + -1X2 = X2 + -1X2

Combine like terms: X2 + -1X2 = 0
2X + -1X2 = 0

Factor out the Greatest Common Factor (GCF), 'X'.
X(2 + -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 '(2 + -1X)' equal to zero and attempt to solve: Simplifying 2 + -1X = 0 Solving 2 + -1X = 0 Move all terms containing X to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1X = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1X = 0 + -2 -1X = 0 + -2 Combine like terms: 0 + -2 = -2 -1X = -2 Divide each side by '-1'. X = 2 Simplifying X = 2

Solution

X = {0, 2}
