How many terms..

jilfer's picture

How many terms will be there in the expression.. and which of these will be the highest one..

[(x-a)(x-b)(x-c)...... (x-z)](234x-535y)^23

This should be fairly easy if you are good in maths...

Next term is ZERO...am I right?

[(x-a)(x-b)(x-c)...... (x-z)](234x-535y)^23

=<(x-a)(x-b)......(x-y)(x-z)> (234x-535y)..23

=(0)(234x-535y)..23
=0
