Given   :  द्विघात समीकरण ax² + bx + c = 0 ; a ≠ 0 के दोनों मूल वास्तविक और बराबर होंगे

To Find :  Correct choice

1️⃣ b² - 4ac = 0

2️⃣ b² - 4ac < 0

3️⃣ b² - 4ac>0

4️⃣ इनमे से कोई नही​

Solution:

ax² + bx + c = 0 ; a ≠ 0 के दोनों मूल वास्तविक और बराबर होंगे

if b² - 4ac = 0

b² - 4ac = 0  is correct answer

b² - 4ac < 0 => roots are not real

b² - 4ac>0  => roots are real and unequal
