I have a question.
I'm doing a cube.
the book says it should be the following.
(a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3
but one of my b variable is delta
(1) unsure how to make delta on the post.
so we will use this to resemble delta
so the actual problem is this.
when cubing this, would i square and cube delta?
