If x and y are integers, then xy(x + y) is
Choose the correct choice from the following answers:
A) Always positive B) Always negative C) Positive when x is positive D) Negative when x is negative E) It cannot be determined by the information given
If you consider the case where x = 0 or y = 0, the result is zero regardless of the value (be it positive or negative) of the other variable.   so given that x &lt; 0 (i.e, x is negative) and y = 0, the result = 0.   Answer is It cannot be determined by the information given
<result>E</result>
