The question states this:
bc(b+c) + ca(c+a) + ab(a+b) > (or equal to) 6abc
These type of question are quite hard for me, as i do not know how to approach it. In easier variations, such as a^2+b^2 >= 2ab, it is easily recognizable. But not so with these questions
If anyone could enlighten me on their process of thought, along with solution, it would be very appreciated.
