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

Step-by-step explanation:

The given expression is

Let us factor the expression.

Factor the GCF of each pair;

Factor again to obtain:

The correct choice is 2x-3

 D) 2x - 3

Step-by-step explanation:

Factor using the Grouping Method

2xy + 6x    +    -3y - 9

2x(y + 3)    +    -3(y + 3)

Since they have a common factor (y + 3), the grouping method can be used - the outside is one factor and the common factor is the other.

⇒ (2x - 3)(y + 3)

2x - 3 is provided as one of the options.  y + 3 is not given as an option

the answer is 15% decrease

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
