Which factorization is equivalent to this expression? 81x−36

−9(9x−4)

9(9x−8)

9x−4

9(9x−4)

The factorization that is equivalent to the expression 81x−36 is 9(9x−4).

The factorization equivalent to the expression 81x - 36 is -9(9x - 4).

To determine the factorization that is equivalent to the expression 81x - 36, we can look for the greatest common factor (GCF) of the terms. In this case, the GCF is 9. To find the equivalent factorization, divide each term by the GCF and place it outside the parentheses.

Dividing 81x by 9 gives us 9x, and dividing -36 by 9 gives us -4. Therefore, the equivalent factorization is:

9(9x - 4)

So, the correct answer is 9(9x - 4).
