The product of three binomials, just like the product of two, can be found with repeated applications of the distributive property.
(a) Find the product: (x - 2)(x + 4)(x - 7) . Use area arrays to help keep track of the product.
(b) For what three values of x will the cubic polynomial that you found in part (a) have a value of zero? What famous law is this known as?
Please help me solve problems A and B.
