The values of x corresponding to assigned values of y always occur in pairs equal in mag- nitude 1 and opposite in sign, since the equation only contains even powers of x; therefore
Since the area of the original big white square is exactly equal to the total area of the light grey squares, the area of the region that’s covered twice must be exactly equal to
