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.
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)
