3n over 2n+9 subtracted by
\n" ); document.write( "6n-5 over 2n+9
\n" ); document.write( ":
\n" ); document.write( "\"%283n%29%2F%28%282n%2B9%29%29\" - \"%28%286n-5%29%29%2F%28%282n%2B9%29%29\"
\n" ); document.write( ":
\n" ); document.write( "They have the same denominator so we can just write it
\n" ); document.write( "\"%28%283n%29-%286n-5%29%29%2F%28%282n%2B9%29%29\"
\n" ); document.write( ":
\n" ); document.write( "remove the brackets (change the sign of 5)
\n" ); document.write( "\"%28%283n-6n%2B5%29%29%2F%28%282n%2B9%29%29\" = \"%28%28-3n%2B5%29%29%2F%28%282n%2B9%29%29\" \n" ); document.write( "
