Hi, can somebody help me with this math problem I am stuck on? How do I use binomial theorem to expand(2x – 5y)^3. I need to show my word so any help you can provide would be greatly appreciated.

Answer 1

Expand

(A + B)^3 = A^3 + 3 A B^2 + 3 A^2B + B^3

And then in this expansion, substitute

A = 2x

B = -5 y

Answer 2

Thank you for your help.
