The Binomial Expansion

In binomial expansion, what order do terms follow when written in ascending powers of xxx?

A

A binomial is an expression containing two terms, such as a+ba+ba+b or 2−5x2-5x2−5x.

B

Constant term (x0x^0x0), followed by x1x^1x1, x2x^2x2, x3x^3x3, etc.

C
  • ax⋅Cax \cdot Cax⋅C
  • b⋅Dxb \cdot Dxb⋅Dx
D

Odd powers of the negative term (−5x-5x−5x) result in negative terms, while even powers result in positive terms.
