\n" ); document.write( " $\"4x%5E2%2F%28%28x%5E2+-+25%29%29\"$ divided $\"2x%2F%28%28x%5E2+%2B+2x+-+15%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Remember when you divide, you invert the dividing fraction and multiply:
\n" ); document.write( " $\"4x%5E2%2F%28%28x%5E2+-+25%29%29\"$ * $\"%28%28x%5E2+%2B+2x+-+15%29%29%2F%282x%29\"$
\n" ); document.write( ":
\n" ); document.write( "do some factoring:

\n" ); document.write( "Do some canceling and we have:
\n" ); document.write( " $\"2x%2F%28%28x-5%29%29%29\"$ * (x-3) = $\"%282x%28x-3%29%29%2F%28%28x-5%29%29%29\"$ = $\"%28%282x%5E2-6x%29%29%2F%28%28x-5%29%29%29\"$ \n" ); document.write( "
