Which is the complete factorization of this expression? 15x−3y

5(3x−y)

3(5x−3)

3(x−3y)

3(5x−y)

The complete factorization of 15x−3y is 3(5x−y).

To find the complete factorization of the expression 15x - 3y, we need to factor out the greatest common factor (GCF) from both terms.

The GCF of 15x and -3y is 3.

Dividing each term by 3, we get:

(15x / 3) - (3y / 3)
= 5x - y

Therefore, the complete factorization is:
3(5x - y)

To find the complete factorization of the expression 15x - 3y, we need to factor out the greatest common factor (GCF) of the given terms. The GCF of 15 and 3 is 3, and the GCF of x and y is 1.

So, we can factor out 3 from both terms:

15x - 3y = 3(5x - y)

Therefore, the complete factorization of the expression 15x - 3y is 3(5x - y).
