Point (1,2) relative to the circle x²+y²+4 x-2 y-4=0 is a/ an

Options

  1. Aexterior point
  2. Binterior point, but not centre
  3. Cboundary point
  4. Dcentre

Correct answer

A. exterior point

Step-by-step solution

We put the co-ordinates of the given point in the given equation of circle x²+y²+4 x-2 y-4=0 At (1,2)(1)²+(2)²+4(1)-2(2)-4=1+4+4-4-4=1>0 Point (1,2) lies out side the circle i.e, an exterior point.
