\n" ); document.write( "\n" ); document.write( "\"%284y%5E2-7y%5E2-2y%5E2%29%2B%28-5y%2B3y-6y%29%2B5\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-5y%5E2-8y%2B5\" Combine like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%284y%5E2-5y%29%2B%283y-7y%5E2%29-%282y%5E2%2B6y-5%29\" simplifies to \"-5y%5E2-8y%2B5\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"%284y%5E2-5y%29%2B%283y-7y%5E2%29-%282y%5E2%2B6y-5%29=-5y%5E2-8y%2B5\" for all values of y.\r
