Ok, more Maths help needed. This is an extension problem but I can't do it, my genius friend can't do it, my friend's father (who's a Maths teacher) can't do it and my father (who studied Maths at Cambridge) can't do it. So I'm putting it to a music forum. Anyway:
A polynomial p(x) divides by x-a, x-b and x-c to leave a, b and c respectively. What is the remainder when p(x) is divided by (x-a)(x-

(x-c)? (a, b and c are distinct)
