    did you enter the right thing into your calculator with brackets in the right place, etc? I don't know how that y got left behind, you know your calculator better than I do.I got the same thing wolfram did.

    It looks like the integration done by your calculator used some integration variable other than x or y .

    Please state in the body of your post the integral you are trying to evaluate.

    Did you put a multiplication symbol, "*", in the middle of "xy"?. It seems that your calculator treated "xy" as the name of a single constant. Thus, your calculator integrated the constant "xy" and got y*xy, After evaluating at the limits, this becomes x*xy.
