# Which expression is a factor of 2xy + 6x − 3y − 9?

Common factors are the parts that are common in the sub-parts of the expression.

## Answer: Common factor in both the sub-divided parts comes out to be (y + 3) so it is a factor of the expression.

Go through the steps to find the common factor.

**Explanation:**

Given expression: 2xy + 6x − 3y − 9

To factories, this expression lets subdivide the 4 terms of the expression, into two each.

Therefore, we can write the same expression as:

= (2xy + 6x) - (3y + 9)

= 2x(y + 3) - 3(y + 3)
