Exercise 42 Page 26

We can find the product of this expression using polynomial identities. In this case, we have the square of a binomial. We will first rewrite the square as the product and then apply the Distributive Property.

Finally, let's identify and combine like terms. 64y^3 - 96y^2z + 36yz^2 + 48y^2z - 72yz^2+ 27z^3 ⇕ 64y^3 - 48y^2z - 36yz^2+ 27z^3
