A curve is traced by a point P(x,y) which moves such that its distance from the point A(1,1) is three times the distance from the point B(2,1). Find the equation of the curve and identity.

distancePB=3distancePA
sqrt((x2)^2+(y+1)^2)=3sqrt((x+1)^2 +(y1)^2)
square both sides, expand the polynomial, collect terms, and you ahve the equation.
