Can you me find area of the shaded region?

If you are solving y2+2y=48 by completing the square, the next line would be y2 + 2y - 48 = 0 y2 + 2y + 4 = 52 y2 + 2y +1 = 49

Which of the following always exist between two objects having mass ● elastic force ● contact force ●gravitational force ●magnetic force
