Question

The locus of all points that are at a distance greater than 2 units from - 3 , 0 , is, ( x , y ) ∣ x 2 + y 2 + 6 x + 5 > 0, ( x , y ) ∣ x 2 + y 2 + 6 x + 7 > 0, ( x , y ) ∣ x 2 + y 2 - 6 x + 5 > 0, ( x , y ) ∣ x 2 + y 2 - 6 x + 5 ≤ 0

MARKS App · Accepted Answer

Let, h , k be the point whose distance from - 3 , 0 is greater than 2 . ⇒ h + 3 2 + k 2 > 2 ⇒ h 2 + k 2 + 6 h + 7 > 0 Replace h by x and k by y ⇒ x 2 + y 2 + 6 x + 7 > 0
