\"sqrt%28x%29%2F+%283%2Asqrt%28x%29+-+sqrt%28y%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " Multiply the fraction by \"%28%283%2Asqrt%28x%29+%2B+sqrt%28y%29%29%2F%283%2Asqrt%28x%29+%2B+sqrt%28y%29%29%29\"\r

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is \"%283%2Ax+%2B+sqrt%28xy%29%29%2F+%289x-y%29\" note: this is just like your last choice, but it has 3x minus the square root instead of 3x plus the square root, so check your choices again. \n" ); document.write( "
