3x2 - 2y2 = 9x2 + 4y2 - 12xy (subtract 3x2 and add 2y2 to both sides)

0 = 9x2 -3x2 + 4y2 + 2y2 - 12xy

0 = 6x2 + 6y2 - 12xy (divide by 6 to both sides)

0 = x2 + y2 - 12xy or

x2 - 2xy + y2 = 0

(x - y)(x - y) = 0

x - y = 0

x = y

Yes, terminal velocity is the highest velocity that a falling object will reach when the force of air resistance equals the force of gravity, resulting in a constant speed.

Does a acorn that falls from a tree reach its terminal velocity?

No, an acorn is too small and light to reach its terminal velocity when falling from a tree. Terminal velocity is the maximum constant speed that an object reaches when the drag force equals the force of gravity, and the small size and weight of an acorn mean that it doesn't experience enough air resistance to reach this terminal velocity.
