\newline

Answer:

Identify Expression Type: Identify the type of expression; $9x^{2}-16$ is a difference of squares because it's in the form $a^2 - b^2$ where $a$ is $3x$ and $b$ is $4$ .
Find Square Roots: Find the square roots of the first and last terms; the square root of $9x^{2}$ is $3x$ and the square root of $16$ is $4$ .
Write Factored Form: Write the factored form using the difference of squares formula, which is $(a + b)(a - b)$ ; so it's $(3x + 4)(3x - 4)$ .
