I assume independent of x means it has no x term and is just a constant.
Then it's a matter of observation. It's 1. Becasue of the 1 in
If you have , just sub in -1/x where the q goes in the expansion. Fractions are no different than an integer.
Hello, i am unsure how to do this question... Find the value of the term in the expansion of (1-1/x)^8 which is independent of x. How do i do this? I have no problem with normal expansions but how do you do one with a fraction in?
Thankyou,
Kris.
