Solution for 12x=15x(x-5) equation:


Simplifying
12x = 15x(x + -5)

Reorder the terms:
12x = 15x(-5 + x)
12x = (-5 * 15x + x * 15x)
12x = (-75x + 15x2)

Solving
12x = -75x + 15x2

Solving for variable 'x'.

Combine like terms: 12x + 75x = 87x
87x + -15x2 = -75x + 15x2 + 75x + -15x2

Reorder the terms:
87x + -15x2 = -75x + 75x + 15x2 + -15x2

Combine like terms: -75x + 75x = 0
87x + -15x2 = 0 + 15x2 + -15x2
87x + -15x2 = 15x2 + -15x2

Combine like terms: 15x2 + -15x2 = 0
87x + -15x2 = 0

Factor out the Greatest Common Factor (GCF), '3x'.

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 '(29 + -5x)' equal to zero and attempt to solve: Simplifying 29 + -5x = 0 Solving 29 + -5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-29' to each side of the equation. 29 + -29 + -5x = 0 + -29 Combine like terms: 29 + -29 = 0 0 + -5x = 0 + -29 -5x = 0 + -29 Combine like terms: 0 + -29 = -29 -5x = -29 Divide each side by '-5'. x = 5.8 Simplifying x = 5.8

Solution

x = {0, 5.8}
