Let a, b, c and d be 4 distinct integers. Find the smallest possible value for [tex] 4(a^2 + b^2 + c^2 + d^2) - (a+b+c+d)^2 [/tex] and prove that your answer is correct.
I got 20 as the smallest answer. Thats when u have a, b, c, and d as 4 consective integers, but i can't prove my answer. Can anyone help? Thanks :)
