Hello, EarlyTravel!
Expand , then find the derivative.
How would I find the derivative? . ??
I don't understand your question.

. . You don't know how to differentiate a polynomial?
. . You don't know the Product Rule?
How about following the directions?
Expand: .
. . . . . . . . . . .
. . . . . . . . . . .
Differentiate: . .[1]
Product Rule:
.
. . . .
. . . .
. . . .
which is equal to [1].
