A square is inscribed in a circle x2 + y2 – 2x + 4y + 3 = 0. Its sides are parallel to the coordinate axes. Then one vertex of the square is
A
(1+2, –2)
B
(1 –2, –2)
C
(1, – 2 +2)
D
None of these
Answer
None of these
Explanation
Solution
Centre є (1, –2), radius =2
So x coordinate of any of the vertices cannot be 1 and y cannot be –2.
