document.write( "For this problem we are going to simplify as much as possible and we want to have expressions that can cancel. We cannot simplify x+2 any further so we keep this the same. We can simplify 7x^2-28 by factoring out a 7 for our greatest common factor and inside parentheses we have x^2-4. We can factor x^2-4 to (x+2)(x-2). Now we have x+2/7(x+2)(x-2). We have x+2 on the top and the bottom so we can cancel those expressions to get 1/7(x-2)as our final answer. Good luck and let me know if you have any more questions :) </SPAN>\n" );
