Solution for 6x=3x(x+78) equation:


Simplifying
6x = 3x(x + 78)

Reorder the terms:
6x = 3x(78 + x)
6x = (78 * 3x + x * 3x)
6x = (234x + 3x2)

Solving
6x = 234x + 3x2

Solving for variable 'x'.

Combine like terms: 6x + -234x = -228x
-228x + -3x2 = 234x + 3x2 + -234x + -3x2

Reorder the terms:
-228x + -3x2 = 234x + -234x + 3x2 + -3x2

Combine like terms: 234x + -234x = 0
-228x + -3x2 = 0 + 3x2 + -3x2
-228x + -3x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
-228x + -3x2 = 0

Factor out the Greatest Common Factor (GCF), '-3x'.
-3x(76 + x) = 0

Ignore the factor -3.

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 '(76 + x)' equal to zero and attempt to solve: Simplifying 76 + x = 0 Solving 76 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-76' to each side of the equation. 76 + -76 + x = 0 + -76 Combine like terms: 76 + -76 = 0 0 + x = 0 + -76 x = 0 + -76 Combine like terms: 0 + -76 = -76 x = -76 Simplifying x = -76

Solution

x = {0, -76}
