Factor. j^2 - 9 ______

Recognize difference of squares: Determine the appropriate method to factor j^2 - 9. We can recognize this expression as a difference of squares, which can be factored using the formula a^2 - b^2 = (a - b)(a + b).Identify expression form: Identify j^2 - 9 in the form of a^2 - b^2. j^2 can be written as (j)^2, and 9 can be written as 3^2, so j^2 - 9 is in the form of (j)^2 - 3^2.Apply formula to factor: Apply the difference of squares formula to factor the expression. Using the formula a^2 - b^2 = (a - b)(a + b), we get: (j)^2 - 3^2 = (j - 3)(j + 3).

j^2 - 9

Recognize difference of squares: Determine the appropriate method to factor $j^2 - 9$ . We can recognize this expression as a difference of squares, which can be factored using the formula $a^2 - b^2 = (a - b)(a + b)$ .
Identify expression form: Identify $j^2 - 9$ in the form of $a^2 - b^2$ . $j^2$ can be written as $(j)^2$ , and $9$ can be written as $3^2$ , so $j^2 - 9$ is in the form of $(j)^2 - 3^2$ .
Apply formula to factor: Apply the difference of squares formula to factor the expression. $\newline$ Using the formula $a^2 - b^2 = (a - b)(a + b)$ , we get: $\newline$ $(j)^2 - 3^2 = (j - 3)(j + 3)$ .
