Show that : a⁴ +b⁴+c⁴ +2a²bc=>2a²b²+2a²c²+ b²c² . (∀ a,b,c ;a,b,c>0). I've been trying to solve his exercise for 2 days, but nothing seems to work . Can someone help me?

I didn't know that I should show any work. I just thought there are passionate persons of math which try to help. How I'm supposed to help other people when I don't know to solve my own exercises?
