Expand. If necessary, combine like terms. (2+x)(2-x)=

Identify special case: Identify the special case that applies here. The expression (2+x)(2-x) is in the form of (a+b)(a-b). Special case: (a+b)(a-b) = a^2 - b^2Identify values of a and b: Identify the values of a and b. Compare (2+x)(2-x) with (a+b)(a-b). a = 2 b = xApply difference of squares: Apply the difference of squares to expand (2+x)(2-x). (a+b)(a-b) = a^2 - b^2 (2+x)(2-x) = 2^2 - x^2Simplify expression: Simplify 2^2 - x^2. 2^2 - x^2 = 4 - x^2

(2+x)(2-x)=

Identify special case: Identify the special case that applies here. $\newline$ The expression $(2+x)(2-x)$ is in the form of $(a+b)(a-b)$ . $\newline$ Special case: $(a+b)(a-b) = a^2 - b^2$
Identify values of $a$ and $b$ : Identify the values of $a$ and $b$ . Compare $(2+x)(2-x)$ with $(a+b)(a-b)$ . $a = 2$ $b = x$
Apply difference of squares: Apply the difference of squares to expand $(2+x)(2-x)$ . $\newline$ $(a+b)(a-b) = a^2 - b^2$ $\newline$ $(2+x)(2-x) = 2^2 - x^2$
Simplify expression: Simplify $2^2 - x^2$ . $\newline$ $2^2 - x^2 = 4 - x^2$
