Need help showing me the steps without using the carrot function:
Find the product.
(2y + 2z)(2y - 3z)

Didn't realize that I had been away from education this long.
What in the world in the carrot function ??

BTW, to expand
(2y + 2z)(2y - 3z) in the ancient mathematical way is
4y^2 - 9z^2 after I realized I was dealing with the difference of square pattern.

Its this symbol^ the computer on our webassign online doesn't recognize it so we need to replace that symbol^with a number so that's where I am lost
