Solution for x(x+5)=x(2x+4) equation:


Simplifying
x(x + 5) = x(2x + 4)

Reorder the terms:
x(5 + x) = x(2x + 4)
(5 * x + x * x) = x(2x + 4)
(5x + x2) = x(2x + 4)

Reorder the terms:
5x + x2 = x(4 + 2x)
5x + x2 = (4 * x + 2x * x)
5x + x2 = (4x + 2x2)

Solving
5x + x2 = 4x + 2x2

Solving for variable 'x'.

Reorder the terms:
5x + -4x + x2 + -2x2 = 4x + 2x2 + -4x + -2x2

Combine like terms: 5x + -4x = 1x
1x + x2 + -2x2 = 4x + 2x2 + -4x + -2x2

Combine like terms: x2 + -2x2 = -1x2
1x + -1x2 = 4x + 2x2 + -4x + -2x2

Reorder the terms:
1x + -1x2 = 4x + -4x + 2x2 + -2x2

Combine like terms: 4x + -4x = 0
1x + -1x2 = 0 + 2x2 + -2x2
1x + -1x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
1x + -1x2 = 0

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

Solution

x = {0, 1}
