Find the product. Simplify your answer. (3y - 1)(3y + 1) ______

Identify Special Case: Identify the special case that applies to the given expression. The expression (3y - 1)(3y + 1) 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 (3y - 1)(3y + 1) with (a - b)(a + b). a = 3y b = 1Apply Difference of Squares Formula: Apply the difference of squares formula to expand (3y - 1)(3y + 1). (a - b)(a + b) = a^2 - b^2 (3y - 1)(3y + 1) = (3y)^2 - (1)^2Simplify Expression: Simplify (3y)^2 - (1)^2. (3y)^2 - (1)^2 = (3y * 3y) - (1 * 1) = 9y^2 - 1

\newline

(3y - 1)(3y + 1)

Identify Special Case: Identify the special case that applies to the given expression. $\newline$ The expression $(3y - 1)(3y + 1)$ 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 $(3y - 1)(3y + 1)$ with $(a - b)(a + b)$ . $a = 3y$ $b = 1$
Apply Difference of Squares Formula: Apply the difference of squares formula to expand $(3y - 1)(3y + 1)$ . $\newline$ $(a - b)(a + b) = a^2 - b^2$ $\newline$ $(3y - 1)(3y + 1) = (3y)^2 - (1)^2$
Simplify Expression: Simplify $(3y)^2 - (1)^2.$ $(3y)^2 - (1)^2 = (3y \times 3y) - (1 \times 1)$ $= 9y^2 - 1$
