Answer:

(x+3)+(5+3y)

Step-by-step explanation: In the equation, when you have four terms you group like terms. So 5x+15 by itself and work it out which you will get 5(x+3) and do the same for 3xy+9y answer is 3y(x+3).

Then you will say 5(x+3)+3y(x+3) and then you'll

5(x+3)/(x+3)=5 because you will cancel the (x+3) so the answer would be 5

You will do the same for 3y(x+3)/(x+3)

you will get 3y

Finally, you will take the first equation which is (x+3), and then you'll use the last equation which is (5+3y)

So that's how you will get (x+3)+(5+3y)

Answer:

(5+3y) (x+3)

first of all you bracket by (5x+15)(3xy+9y). and you start fact as follows by 5(x+3y) 3y(x+3)after here you take (5+3y) (x+3)
