Consider the product (x + y + z)2. if the expression is multiplied out and like terms collected, the result is: x2 + y2 + z2 + 2xy + 2yz + 2xz suppose we do the same to the product (v + w + x + y + z)25 (a) what is the coefficient of the term v9w2x5y7z2? (b) how many different terms are there? (two terms are the same if the degree of each variable is the same.)
