I have my next E1 (Yr 12) exam on binomial theorem (It really is just a ton of 2u topics and also binomial theorem, real weird)
Would anyone be able to give me some good questions? Just to give an example of the type of questions I am looking for, the following was a sample question on the notification (So a decent bit easier than what will come in the exam. We will be doing integration and differentiation and geometric series of these)
By taking

Prove

Where nCx is n choose x (I know the answer to the above, but I was wondering if you guys had any other ones that weren't from HSC past papers)

Thanks!

Take a look at the bos 3u trials in the resources section. You won’t find any questions harder than that.

Use fact: coeff of term in x^n of LHS = coeff of term in x^n of RHS and note fact that nCr = nCn-r.

Where do I find those trials? (Both the ones from last year and earlier years?)

See the yellow sticky which has the hyperlink and go to the relevant subject
