Mathematics problems of senior two (track equation) Let m be the moving point on the circle x ^ 2 + y ^ 2-6x-8y = 0, o be the origin, n be the point on the ray OM, if | om | x | on | = 120, Find the trajectory equation of n points

The deformation of circle m is (x-3) ^ 2 + (y-4) ^ 2 = 25
Since the coordinates of the origin conform to the M equation of the circle, M is on the circle
OM is the radius, so | om | = 5
So | on | = 24
So point n is a circle with o as the center and 24 as the radius
So the trajectory equation of n is x ^ 2 + y ^ 2 = 576
