the answer is 2(x+3y)^2

Explanation:

first you find the GCF(greatest common factor) and that will be 2 so you'll get2(x^2+6xy+9y^2) and the rest inside is from what you get when you multiply 2 and the rest. now you have to figure out what two numbers that multiply to give you 9 and add to 6 so 3,3 and now you'll get 2(x+3y^2) i shortened it but you don't have to if you havex^2, you don't have to do the long way, you can just figure it out from there. but this one, there's two 3s so you can just put it like this2(x+3y^2)
