(x+y)^3 expansion
(x+y)^3 expansion-It can never be $3^n$ As you can see for $(ab)^n$ contains just $n1$ terms Note that we have to keep the sum of powers in each of the combinations of $x,y,z$ to $n$, so it will be reduced Now replace $a$ and $b$ by $x$ and $(yz)$ respectively So total number of terms should be $123\cdots(n1)=\dfrac{(n1)(n2)}{2}$You can use f(x,y) for the function if you prefer, but that's one more letter to keep track of
