$\"-5%28x-3y%29%5E2+%2B+7%283y-x%29=-5%28x-3y%29%5E2+-7%28x-3y%29\"$
\n" ); document.write( "That makes you see a $\"%28x-3y%29\"$ common factor, so
\n" ); document.write( " $\"-5%28x-3y%29%5E2+%2B+7%283y-x%29=%28x-3y%29%28-5%28x-3y%29-7%29\"$
\n" ); document.write( " $\"-5%28x-3y%29%5E2+%2B+7%283y-x%29=highlight%28%28x-3y%29%28-5x%2B15y-7%29%29\"$
\n" ); document.write( "There are other equivalent alternative factored forms,
