Show answer and explanation
Correct Answer
A. (1 2) / (1 2)
ExplanationStep 1: Identify circle form (x-h)² + (y-k)² = r². Step 2: h = 1 and k = 2 so centre is (1 2). Step 3: Get used to reading signs inside brackets carefully.
Step 1: Circle form (x-h)² + (y-k)² = r² पहचानें। Step 2: h = 1 और k = 2 इसलिए center (1 2) है। Step 3: Bracket में sign उल्टा पढ़ने की आदत रखें।
