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.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
