Question 110Asked in BPSC TRE 1.0 (2023) Mathematics Class 9-10

The quadratic equation ax² + bx + c = 0 (a ≠ 0) has two distinct real roots ifद्विघात समीकरण ax² + bx + c = 0 (a ≠ 0) दो भिन्न वास्तविक मूल रखता है, यदि

द्विघात समीकरण ax² + bx + c = 0 (a ≠ 0) दो भिन्न वास्तविक मूल रखता है, यदि
  1. Athe discriminant > 0विविक्तकर > 0
  2. Bthe discriminant = 0विविक्तकर = 0
  3. Cthe discriminant < 0विविक्तकर < 0
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं
Show answerHide answer

Correct answer: (A) the discriminant > 0विविक्तकर > 0

Explanation

A quadratic has two distinct real roots exactly when its discriminant is positive.द्विघात समीकरण के दो भिन्न वास्तविक मूल तभी होते हैं जब विविक्तकर धनात्मक हो।
