\n" ); document.write( ":
\n" ); document.write( " $\"%28%287x%2B1%29%29%2F%28%28x%5E2-9%29%29\"$ - $\"5%2F%28%28x-3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "You should recognize that (x^2-9) is the difference of squares and can be factored
\n" ); document.write( " $\"%28%287x%2B1%29%29%2F%28%28x%2B3%29%28x-3%29%29\"$ - $\"5%2F%28%28x-3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "The common denominator would be (x-3)(x+3) so you would have:
\n" ); document.write( " $\"%28%287x%2B1%29-5%28x%2B3%29%29%2F%28%28x%2B3%29%28x-3%29%29\"$ = $\"%287x+%2B+1+-+5x+-+15%29%2F%28%28x%2B3%29%28x-3%29%29\"$ = $\"%282x+-+14%29%2F%28%28x%2B3%29%28x-3%29%29\"$ or $\"%282x+-+14%29%2F%28%28x%5E2+-+9%29%29\"$ \n" ); document.write( "
