How do I go about determining the coefficient of the middle term in the expansion of (2x-3)^10

⚑ Flag

This is a binomial expansion. using the tenth row of Pascal's triangle, there are 10C0 x^10 terms, 10C1 x^9 terms, 10C2 x^8 terms...and so on.Note that the notation "10C2" just means "10 choose 2". I'm guessing that you have just learned about this in class OR are about to learn it soon.The "middle term" is the x^5 term. It is 10C5 * (2x)^5 * (-3)^5.
