3times the sum of x and y squared plus 5 times the difference of 2x and y

3x + xy^2 + 5x - 2xy     ok so once you can decode the sentence this is what it will look like.    First you add the common facts which are 3x and 5x which = 8x ok so now we have 8x + xy^2 - 2xy so then I believe you cant do anything after that because there will be no more common factors hey can you tell me if I am write if you have already had turn this in please hope this helps
