Question

How to factorize
》( b-c)^3 + ( c-d )^3 + ( d-b )^3

Answer 1

The picture above has the answer. I tried finding a formula for a^3+b^3+c^3 but I couldn't find it in the Internet, however I think I made a formula for that in the past, but I just don't remember and will have to find my old notebook for the formula. I hope that the answer helps you
