Question

Find the equation of locus of point P, if the points A (1,2), B (3,4) are at equal distance from P.

Answer 1

Heya....

Here's your answer....

let A &B two complex no’s 1+2i and 3+4i respectively..

and let z=x+iy be a complex no which is equidistant with A&B .

so,

|z-(1+2i)|=|z-(3+4i)|

=|x+iy-(1+2i)|=|x+iy-(3+4i)|

=(x-1)^2+(y-2)^2=(x-3)^2+(y-4)^2

=4x+4y=20

=x+y=5 answer..

Thanks...!!!
