find the product. simplify your answer. (2x + 4)(2x - 4)

Explanation:

Step1: Apply difference - of - squares formula

We use the formula $(a + b)(a - b)=a^{2}-b^{2}$. Here $a = 2x$ and $b = 4$. $(2x + 4)(2x - 4)=(2x)^{2}-4^{2}$

Step2: Calculate squares

$(2x)^{2}=4x^{2}$ and $4^{2}=16$. $4x^{2}-16$

Answer:

$4x^{2}-16$
