Question

64. A points P moves such that its distances from
(1, 2) and (-2,3) are equal. Then, the locus of Pis

(a) straight line (b) parabola (c) ellipse (d) hyperbola​

Answer 1

Answer:

Step-by-step explanation:

⇒P(n,y),

⇒A:(1,2),

⇒B:(-2,3),

⇒PA²=PB²,

⇒(n-1)²+(y-2)²=(n+2)²+(y-3)²,

⇒n²+1-2n+y²+μ-μy=n²+μ+μn+y²+y-6y,

⇒6n-2y+8=0,

⇒3x-y+μ=0.

Hope it helps
