Explanation:

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:

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