Question 725385
this factors to:


x * (x^2 + 6x + 9) divided by x * (x^2 - 9) which factors to:


x * (x + 3) * (x + 3) divided by x * (x + 3) * (x - 3)


The x in the numerator and denominator cancel out.


The (x + 3) in the numerator and denominator cancel out.


you are left with:


(x + 3) / (x - 3)


that's the simplified equation.


the restrictions come from the original factored equation, which is:


x * (x + 3) * (x + 3) divided by x * (x + 3) * (x - 3)


x in the denominator can't be equal to 0.


x can't be equal to -3, otherwise (x + 3) in the denominator would be equal to 0.

x can't be equal to 3, otherwise (x - 3) in the denominator would be equal to 0.
