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.

1 answer

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.
