GMAT Quantitative Reasoning Practice Test 7

Statement (1) can be written as $\left(\mathit{X}-4\right)\left({\mathit{X}}^2+\mathit{X}+2\right)=0$.
The roots of this equation are one integer and two complex numbers, which you should pay no attention to since you were told that $\mathit{X}$ is an integer.
Statement (2) is a simple equation, $\mathit{Y}=4$.
The value of the expression $\mathit{X}\mathit{Y}$ is 16 .
Both statements, taken together, are sufficient to answer the question.
