Find all solutions, FACTOR FIRST

Find all solutions, FACTOR FIRST

Solution

The given equation is:

x32x23x=0x^3 - 2x^2 - 3x = 0

We are tasked to factor the equation first and then solve for xx.


Step 1: Factor the equation

Start by factoring out the greatest common factor (GCF) of all terms, which is xx: x(x22x3)=0x(x^2 - 2x - 3) = 0

Next, factorize the quadratic expression x22x3x^2 - 2x - 3. Look for two numbers whose product is 3-3 and sum is 2-2. These numbers are 3-3 and 11.

Thus: x22x3=(x3)(x+1)x^2 - 2x - 3 = (x - 3)(x + 1)

So the fully factored form of the equation is: x(x3)(x+1)=0x(x - 3)(x + 1) = 0


Step 2: Solve for xx

Set each factor equal to zero:

  1. x=0x = 0
  2. x3=0    x=3x - 3 = 0 \implies x = 3
  3. x+1=0    x=1x + 1 = 0 \implies x = -1

Final Solution:

The solutions to the equation are: x=0,x=3,x=1x = 0, \quad x = 3, \quad x = -1
