You can put this solution on YOUR website!
by factoring the values under the radical signs, you make perfect squares that can be extracted

3sqrt%282%2A4x%5E2%2Ay%2Ay%5E2%29%2B2x%2Asqrt%282%2A16%2Ay%2Ay%5E2%29

3%2A2xy%2Asqrt%282y%29%2B2x%2A4y%2Asqrt%282y%29 ... 6xy%2Asqrt%282y%29%2B8xy%2Asqrt%282y%29

14xy%2Asqrt%282y%29
