Solution

Let P (x, y, z) be any point which is equidistant from A (3,4,5) and B (-2,1,4) .Then,
PA = PB
x-32+y-42+z+52=x+22+y-12+z-42x2-6x+9+y2-8y+16+z2+10z+25=x2+4x+4+y2-2y+1+z2-8z+16x2-6x+9+y2-8y+16+z2+10z+25=x2+4x+4+y2-2y+1+z2-8z+16-10x-6y+18z+29=010x+6y-18z-29=0

Hence, 10x + 6y -18z -29 = 0 is the required equation.
