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

 

 

i promise I will wait for a long interval of time before posting now so other people can get answers to their questions, again I am very sorry

(x^2 -4x + 4 ) (x^2 + 4x +4 )

 

x^4 + 4x^3 + 4x^2       - 4x^3 - 16x^2 - 16x      + 4x^2 + 16x + 16

 

x^4 - 8x^2 + 16               coefficients  of   1  - 8    and constant of 16

What would be the product of the constants and coefficients

Multiply them together to get the product.....      1  ,   -8    ,   16
