\"x%5E2%2F%28x-3%29\" - \"9%2F%28x-3%29\"
\n" ); document.write( "They have the same denominators so you can write it:
\n" ); document.write( "\"%28x%5E2-9%29%2F%28x-3%29\"
\n" ); document.write( "(x^2-9) is the difference of squares, so we can factor it, then cancel:
\n" ); document.write( "\"%28%28x-3%29%28x%2B3%29%29%2F%28x-3%29\" = (x+3)
\n" ); document.write( "
\n" );
