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

\((x-2)^2(x+2)^2\)

 

The easiest way to do this is to rearrange it as follows.

 

\((x-2)^2(x+2)^2=(x-2)(x+2)*(x-2)(x+2)\)

 

that is a good start for you.
