i) Given that , find the value of A, of B and of C.
ii) Hence using the substitution , solve for , the equation

I wonder if there is a direct way to solve the problem without expansion, which is evidently not the right approach.
No, I will not solve the question in steps. That's against the policy of the site. This is for YOU to do.
I suggest you read about Pascal's Triangle. The notation stands for "row , position " in the triangle (and the 1 at the top counts as row 0). Then you can write
which is the simplified version for the Binomial Expansion I showed you earlier.
That a great guide.
Yes, indeed Sir, to solve Polynomials with larger powers ... the only handy way is Binomial Theorem. I need to get used to that more often.
Thanking you and Soroban a lot.
