For the example in the explanation the result is:

\boxed{E=-1}

<h2>Explanation:</h2>

Hello! remember to write complete questions in order to find good and exact answers. Here you haven't provided any expression so I'll help you writing an expression. Suppose your expression is:

E=XY^2+2Y+X

So in order to know the value of our expression E, we need to substitute both x and y in it, so:

E=XY^2+2Y+X \\ \\ E=(-1)(2)^2+2(2)-1 \\ \\ E=-4+4-1 \\ \\ \boxed{E=-1}
