(A) To find the product of $(3-2 x)(3+2 x)$,we use the algebraic identity: $(a-b)(a+b) = a^{2}-b^{2}$.Here,$a = 3$ and $b = 2x$.Substituting these values into the identity:$(3-2 x)(3+2 x) = (3)^{2} - (2x)^{2}$.Calculating the squares:$(3)^{2} = 9$ and $(2x)^{2} = 4x^{2}$.Therefore,the product is $9 - 4x^{2}$.
