    no, then it would be like this: \[2(x+y)\] you would do the parenthesis first: \[2(xy)\] then you would multiply them, thus the final answer is:\[(2xy)\]

    so 2(x+y) for the first part and then (2xy) for the second part?

    okay, so i reread the questinon, the first one, like you said was 2xy, while twice the sum of x and y would be:2(x)+2(y)=4xy i think...
