Expand. If necessary, combine like terms. (x+8)(x-8)=

Identify special case: Identify the special case that applies to the given expression. The expression (x+8)(x-8) 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 (x+8)(x-8) with (a + b)(a - b). a = x b = 8Apply difference of squares formula: Apply the difference of squares formula to expand (x+8)(x-8). (a + b)(a - b) = a^2 - b^2 (x + 8)(x - 8) = x^2 - 8^2Simplify expression: Simplify x^2 - 8^2. x^2 - 8^2 = x^2 - 64

(x+8)(x-8)=

Identify special case: Identify the special case that applies to the given expression. $\newline$ The expression $(x+8)(x-8)$ 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 $b$ . $\newline$ Compare $(x+8)(x-8)$ with $(a + b)(a - b)$ . $\newline$ a = $x$ $\newline$ b = $8$
Apply difference of squares formula: Apply the difference of squares formula to expand $(x+8)(x-8)$ . $\newline$ $(a + b)(a - b) = a^2 - b^2$ $\newline$ $(x + 8)(x - 8) = x^2 - 8^2$
Simplify expression: Simplify $x^2 - 8^2$ . $\newline$ $x^2 - 8^2 = x^2 - 64$
