Homework Help: algebra story problems

You have a metal plate that you have drilled a hole into. The entire area enclosed by the metal plate is given by 5x^2 = 12x + 10 and the area of the hole is given by x^2+2. Write an expression for the area in factored form of the plate that is left after the hole is drilled.

The sentence "The entire area enclosed by the metal plate..." makes little sense. What is x? IF x is the area, then you have to solve for it in that equation, then subtract by something (if area is x, then you cant subtract x^2+2 from it.

I think someone goofed in constructing this problem.
