Hey, you did great with your parentheses this time.

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

Even after we simplify the expression, we must make restrictions to make sure
that there are no numbers we could substitute for x that would cause the
original expression to be undefined by dividing by 0. 

Therefore, 
EACH TIME WE CANCEL ANY FACTOR, WE MUST MAKE A RESTRICTION THAT PREVENTS THE
CANCELED EXPRESSION FROM EVER BEING EQUAL TO ZERO.  ALSO IN THE FINAL
SIMPLIFICATION, WE MUST MAKE A RESTRICTION THAT PREVENTS ITS DENOMINATOR
FROM BEING EQUAL TO ZERO.

 divided by  

Invert and multiply:



Factor:


We cancel the (3x+8)'s



We must indicate the restriction that x cannot equal -8/3.



We cancel one of the (x+3)'s and indicate the restriction





We cancel the other pair of (x+3)'s.  [We've already indicated this restriction,
so we don't need to indicate it again.]



The final simplification is



We must also indicate that the denominator of the final simplification to
prevent it from ever being 0.




So putting in all the restrictions:
