Expand the product (x - 2)^2  (x + 2)^3. What is the product of the nonzero coefficients of the resulting expression, including the constant term?

(x - 2)^2  =  x^2  - 4x  +  4

 

( x + 2)^3  =   x^3  + 3 * x^2 *2   +  3x*2^2   +  2^3  =   x^3  + 6x^2 + 12x  +  8

 

Product   =   (1)  (-4) ( 4)  ( 1 ) ( 6) ( 12) ( 8)     =  -9216
