Please ANSWER!!

The area of a poster board is x^2 + 3x - 10 inches.
The width is x - 2 inches.
Select the polynomial for the area of the poster board if one inch is removed from each side.

I'm pretty sure its not the first or the second so which is it!?!
x^2 + x + 12

x^2 + 2x + 12

x^2 - x - 12

x^2 + x - 12
