3 radical a + 9 radical b+ radical b + 2 radical a
3sqrt%28a%29+%2B+9sqrt%28b%29+%2B+sqrt%28b%29+%2B+2sqrt%28a%29
Group like terms and add them
3sqrt%28a%29+%2B+2sqrt%28a%29+%2B+9sqrt%28b%29+%2B+sqrt%28b%29 = 5sqrt%28a%29+%2B+10sqrt%28b%29
you can factor out 5 if you want to
5%28sqrt%28a%29+%2B+2sqrt%28b%29%29
