If ax + by + c = 0 is the polar of (1,1)...

If `ax + by + c = 0` is the polar of `(1,1)` with respect to the circle `x^(2) + y^(2) - 2x + 2y `
`+ 1 = 0` and H. C. F. of a, b, c is equal to
one then find `a^(2) + b^(2) + c^(2) .`

Text Solution

Verified by Experts

The correct Answer is:
`a^(2) + b^(2) + c^(2) = (1)^(2) = 5`
