Factor. h^2 - 9 ______

Determine Factoring Technique: Determine the appropriate factoring technique for h^2 - 9. Since we have a difference of squares, we can use the formula a^2 - b^2 = (a - b)(a + b).Identify Form of a^2 - b^2: Identify h^2 - 9 in the form of a^2 - b^2. h^2 can be written as (h)^2, and 9 can be written as 3^2, which means h^2 - 9 is in the form of a^2 - b^2 where a = h and b = 3.Apply Difference of Squares Formula: Apply the difference of squares formula to factor h^2 - 9. Using the formula a^2 - b^2 = (a - b)(a + b), we get (h)^2 - 3^2 = (h - 3)(h + 3).Write Final Factored Form: Write the final factored form. The factored form of h^2 - 9 is (h - 3)(h + 3).

h^2 - 9

Determine Factoring Technique: Determine the appropriate factoring technique for $h^2 - 9$ . Since we have a difference of squares, we can use the formula $a^2 - b^2 = (a - b)(a + b)$ .
Identify Form of $a^2 - b^2$ : Identify $h^2 - 9$ in the form of $a^2 - b^2$ . $h^2$ can be written as $(h)^2$ , and $9$ can be written as $3^2$ , which means $h^2 - 9$ is in the form of $a^2 - b^2$ where $a = h$ and $h^2 - 9$ $0$ .
Apply Difference of Squares Formula: Apply the difference of squares formula to factor $h^2 - 9$ . Using the formula $a^2 - b^2 = (a - b)(a + b)$ , we get $(h)^2 - 3^2 = (h - 3)(h + 3)$ .
Write Final Factored Form: Write the final factored form. $\newline$ The factored form of $h^2 - 9$ is $(h - 3)(h + 3)$ .
