6sqrt%2850x%5E2y%29+-+3x%2Asqrt%288y%29
Simplify it, remove as much as possible from the radicals. Look for terms that are squared.
6sqrt%2825x%5E2%2A2y%29+-+3x%2Asqrt%284%2A2y%29
= 6%2Asqrt%2825x%5E2%29%2Asqrt%282y%29+-+3x%2Asqrt%284%29%2Asqrt%282y%29
= 6%2A5x%2Asqrt%282y%29+-+3x%2A2%2Asqrt%282y%29
= 30x%2Asqrt%282y%29+-+6x%2Asqrt%282y%29
= 24x%2Asqrt%282y%29
