Hi everybody!
Could somebody please assist me with these questions? I've been trying to do them for a while now and I am pretty frustrated. Not getting the right answer :{


9. (a) Find the locus of the point P(x, y) whose distance from the point A(4, 0) is always
twice its distance from the point B(1, 0).

(b) Find the locus of the point P(x, y) whose distance from the point A(2, 5) is always
twice its distance from the point B(4,−1).

Thanks alot!

Expand both sides, collect like terms and complete the square is necessary.
