Find the expansion of (r + 4)</I>3
I have the hardest time ever with this topic. I need a good, clear explanation on how to expand these (for someone who's an apparent math moron).
Hello, BlueStar!
The very least you could do is mutliply it out . . .Find the expansion of: .
First, find
. .
The multiply by another
. .
If you are seeking a shortcut to this type of multiplication,
. . then you want the Binomial Theorem (or Binomial Expansion).
Perhaps someone will explain it to you . . . or not.
