Find the product. Simplify your answer. (2r - 2)(2r + 2) ______

Identify values: Identify the values of a and b. Compare (2r - 2)(2r + 2) with (a - b)(a + b). a = 2r b = 2Apply formula: Apply the difference of squares formula to expand (2r - 2)(2r + 2). (a - b)(a + b) = a^2 - b^2 (2r - 2)(2r + 2) = (2r)^2 - (2)^2Simplify expression: Simplify (2r)^2 - (2)^2. (2r)^2 - (2)^2 = (2r * 2r) - (2 * 2) = 4r^2 - 4

Q. Find the product. Simplify your answer.

\newline

(2r - 2)(2r + 2)

Identify values: Identify the values of $a$ and $b$ . Compare $(2r - 2)(2r + 2)$ with $(a - b)(a + b)$ . $a = 2r$ $b = 2$
Apply formula: Apply the difference of squares formula to expand $(2r - 2)(2r + 2)$ . $\newline$ $(a - b)(a + b) = a^2 - b^2$ $\newline$ $(2r - 2)(2r + 2) = (2r)^2 - (2)^2$
Simplify expression: Simplify ($2r)^ $2$ - ( $2$ )^ $2$ .(\newline$($2r)^ $2$ - ( $2$ )^ $2$ (\newline$= ( $2$ r \cdot $2$ r) - ( $2$ \cdot $2$ )(\newline\)= $4$ r^ $2$ - $4$
