Question 8309
({{{(x^2 + 5x + 4) / (x + 3)^2}}} )  ÷ ({{{( x + 1) / (x^2 - 9)}}})


=({{{(x+4)(x+1) / (x + 3)(x+3)}}} )  ÷ ({{{( x + 1) / (x-3)(x+3)}}})


=({{{(x+4)(x+1) / (x + 3)(x+3)}}} )  * ({{{(x-3)(x+3)/(x+1)}}})


=({{{(x+4)(x+1)(x-3)(x+3)/(x+1)(x + 3)(x+3)}}} )  


=({{{(x+4)(x-3)/(x + 3)}}} )
