Show that 8 - 10 + 21= 0, Mathematics

Assignment Help:

If A, B and P are the points (-4, 3), (0, -2) and (α,β) respectively and P is equidistant from A and B, show that 8α - 10β + 21= 0.

Ans :  AP = PB ⇒ AP2 = PB2

(∝ + 4)2 + (β - 3)2 = ∝2  +(β + 2)2

2  + 8∝ + 16 + β2 - 6β + 9 = ∝2  + β2 + 4β + 4

8∝ - 6β - 4β + 25 - 4 = 0

8∝ - 10β + 21 = 0
