Given the circles $x^2 + y^2 - 4x - 5 = 0$ and $x^2 + y^2 + 6x - 2y + 6 = 0$. Let $P$ be a point $(\alpha, \beta)$ such that the lengths of the tangents from $P$ to both circles are equal. Then:

  • A
    $2\alpha + 10\beta + 11 = 0$
  • B
    $2\alpha - 10\beta + 11 = 0$
  • C
    $10\alpha - 2\beta + 11 = 0$
  • D
    $10\alpha + 2\beta + 11 = 0$
