Choose the correct alternative.
The equation of tangent to the curve x2 + y2 = 5 where the tangent is parallel to the line 2x – y + 1 = 0 are
विकल्प
2x – y + 5 = 0; 2x – y – 5 = 0
2x + y + 5 = 0; 2x + y – 5 = 0
x – 2y + 5 = 0; x – 2y – 5 = 0
x + 2y + 5 = 0; x + 2y – 5 = 0
उत्तर
2x – y + 5 = 0; 2x – y – 5 = 0
