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).
