Solution for 3x(2x-3)=x(x+1) equation:


Simplifying
3x(2x + -3) = x(x + 1)

Reorder the terms:
3x(-3 + 2x) = x(x + 1)
(-3 * 3x + 2x * 3x) = x(x + 1)
(-9x + 6x2) = x(x + 1)

Reorder the terms:
-9x + 6x2 = x(1 + x)
-9x + 6x2 = (1 * x + x * x)
-9x + 6x2 = (1x + x2)

Solving
-9x + 6x2 = 1x + x2

Solving for variable 'x'.

Reorder the terms:
-9x + -1x + 6x2 + -1x2 = 1x + x2 + -1x + -1x2

Combine like terms: -9x + -1x = -10x
-10x + 6x2 + -1x2 = 1x + x2 + -1x + -1x2

Combine like terms: 6x2 + -1x2 = 5x2
-10x + 5x2 = 1x + x2 + -1x + -1x2

Reorder the terms:
-10x + 5x2 = 1x + -1x + x2 + -1x2

Combine like terms: 1x + -1x = 0
-10x + 5x2 = 0 + x2 + -1x2
-10x + 5x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-10x + 5x2 = 0

Factor out the Greatest Common Factor (GCF), '5x'.
5x(-2 + x) = 0

Ignore the factor 5.

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 + x)' equal to zero and attempt to solve: Simplifying -2 + x = 0 Solving -2 + x = 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 + x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + x = 0 + 2 x = 0 + 2 Combine like terms: 0 + 2 = 2 x = 2 Simplifying x = 2

Solution

x = {0, 2}
