Factor the expression 49x^2 42xy+9y^2 into a product of binomials.
So far I have (7x9y)(7x9y) I think the 9y is wrong but I do not know what to change it to then? Help?

Best ResponseYou've already chosen the best response.2That's a perfect square trinomial, and it factors to\[(7x  3y)^{2}.\]

Best ResponseYou've already chosen the best response.0I was just thinking maybe that last part is 3y. How would I show my work on this? Do I check it by doing FOIL?
