What is the expression in factored form?

9x2−4 show all work

To express the expression 9x^2 - 4 in factored form, we can use the difference of squares formula.

The formula states that a^2 - b^2 = (a + b)(a - b).

In this case, a = 3x and b = 2.

So, the expression in factored form is: (3x + 2)(3x - 2).
