Which factorization is equivalent to this expression
81x - 36
The factorization that is equivalent to the expression 81x - 36 is:
9(9x - 4)
To find the factorization equivalent to the expression 81x - 36, we need to factor out the greatest common factor (GCF) of the two terms.
Step 1: Find the GCF.
The GCF of 81x and 36 is 9 because both terms are divisible by 9.
Step 2: Divide each term by the GCF.
Dividing 81x by 9 gives us 9x.
Dividing 36 by 9 gives us 4.
Therefore, the equivalent factorization of 81x - 36 is:
9(9x - 4)
To find the equivalent factorization of the expression 81x - 36, we can look for a common factor that we can factor out from both terms. In this case, 9 is a common factor:
81x - 36 = 9(9x - 4)
So, the equivalent factorization of 81x - 36 is 9(9x - 4).
