1.

A(3,0)and B(-3,0) are two fixed points. find the locus of a moving point P such that PA is perpendicular to P B​

Answer»

ong>Answer:P>

{x}^{2}  +  {y}^{2}  = 9

Step-by-step explanation:

let the co coordinate OS P be (x,y)

given PA is PERPENDICULAR to PB

therefore the multiplication of their is equal to -1

\frac{y}{x - 3}  \times  \frac{y}{x + 3}  =  - 1 \\  {y}^{2}   = 9 -  {x}^{2}  \\  \\  {x}^{2}   + {y}^{2}  = 9
