Find the 6th term in the expansion of (2x - Y)^12.
Added by David W.
Step 1
The binomial theorem states that: (a + b)^n = C(n, 0) * a^n * b^0 + C(n, 1) * a^(n-1) * b^1 + ... + C(n, n) * a^0 * b^n where C(n, k) is the number of combinations of n items taken k at a time, also written as n! / (k!(n-k)!). In our case, a = 2x, b = -y, and n Show more…
