Hey there!

Just as a review, we know that when variables are next to each other, they're being multiplied. Therefore, when we plug in these values, they're being multiplied. We have x as -6 and y as 2, and plugging these in, we get:

14 - 2(-6)(2) =

Remember, a negative number times a negative number is a positive number. That two is negative because it's being subtracted and has a negative sign in front of it.

14 + 12(2) =

12 + 24 =

36

Therefore, your answer is 36.

Hope this helps!

You can substitute x and y to -6 and 2 respectively
So that would be 14 - 2(-6)(2) = 14 + 24 = 38

Final answer: 38
