Well, it looks like you haven't lost your touch.
\n" ); document.write( "Your initial step was quite correct. I am assuming that the task is to simplify the given expression.
\n" ); document.write( " $\"%28%28x%5E2-64%29%2F%285x%29%29%28%2810x%5E2%29%2F%28x%2B8%29%29\"$ You correctly factored the numerator of the first fraction.
\n" ); document.write( " $\"%28%28%28x%2B8%29%28x-8%29%29%2F%285x%29%29%28%2810x%5E2%29%2F%28x%2B8%29%29\"$ and you also correctly cancelled the (x+8)'s
\n" ); document.write( " $\"%28%28x-8%29%2F%285x%29%29%28%2810x%5E2%29%2F1%29\"$ At this point, you can cancel 5x's in the denominator and from the $\"10x%5E2\"$ in the numerator.
\n" ); document.write( " $\"%288-x%29%282x%29\"$ Finally, you can multiply these two factors.
\n" ); document.write( " $\"16x-2x%5E2\"$ \n" ); document.write( "

\n" );
