Which is the complete factorization of this expression
15x -3y
The complete factorization of the expression 15x - 3y is 3(5x - y).
The expression 15x - 3y can be factorized by finding the greatest common factor (GCF) of the coefficients 15 and -3, as well as the variables x and y.
We can see that the GCF of 15 and -3 is 3.
Therefore, the complete factorization of the expression 15x - 3y is:
3(5x - y)
To find the complete factorization of the expression 15x - 3y, we need to look for the greatest common factor (GCF) of the coefficients in front of each variable.
Step 1: Find the GCF of 15 and 3.
The factors of 15 are 1, 3, 5, 15.
The factors of 3 are 1, 3.
The GCF of 15 and 3 is 3.
Step 2: Divide each term by the GCF.
Dividing 15x by 3 gives us 5x.
Dividing -3y by 3 gives us -y.
Step 3: Write the expression using the GCF and the divided terms.
The complete factorization of 15x - 3y is 3(5x - y).
