%28+x%5E2-2x+%29%28+x+%2B+3%29+=+-2x+%28+x+%2B+1%29+ Start with the given equation


x%5E3%2B3x%5E2-2x%5E2-6x+=+-2x+%28+x+%2B+1%29+ FOIL


x%5E3%2B3x%5E2-2x%5E2-6x+=+-2x%5E2-2x+ Distribute


x%5E3%2B3x%5E2-2x%5E2-6x%2B2x%5E2%2B2x=0 Get everything to the left side


x%5E3%2B3x%5E2-4x=0 Combine like terms.


x%28x%5E2%2B3x-4%29=0 Factor out the GCF "x"


x=0 or x%5E2%2B3x-4=0 Set each factor equal to zero


So the first solution is x=0

---------------------

Now let's solve x%5E2%2B3x-4=0


%28x%2B4%29%28x-1%29=0 Factor the left side


x%2B4=0 or x-1=0 Set each factor equal to zero


x=-4 or x=1 Solve for "x" in each equation



========================================================
Answer:


So the solutions are x=0, x=-4, or x=1
