Factorization...

Factorise:   a^4(b^2-c^2)+b^4(c^2-a^2)+c^4(a^2-b^2).

Thanks in advance up

Re: Factorization...

Multiply out all the terms, then combine.  What are you having trouble with?

Please don't just post asking us to do the work for you.  Show that you made an attempt, and ask questions on what you are having trouble with.

Re: Factorization...

The answer is (a+b)(a-b)(b+c)(b-c)(c+a)(c-a).

Right?
