The binomial coefficient is CNR, and the coefficient in the expansion is the product of CNR and X
For example: C51 (2x) (5 below 1 above, you can understand it),
Its binomial coefficient is C51, and its expansion coefficient is C51 × 2 = 10
I am in senior three, in the general review, here has not reviewed, the answer is not perfect, but the general meaning is that
