Answer:

The product of (x+3)(x-3) is x²-9

Step-by-step explanation:

Given: (x+3)(x-3)

We need to find the product of the two factor.

Using distributive property

(a+b)(c+d) = ac+ad+bc+bd

(x+3)(x-3)=x(x-3)+3(x-3)

\Rightarrow x^2-3x+3x-9

Cancel like terms

\Rightarrow x^2-9

Hence, The product of (x+3)(x-3) is x²-9
