किस समीकरण के वास्तविक मूल नहीं होंगे?
Which equation will have no real roots?
Explanation opens after your attempt
Correct Answer
A. \(x^2+3x+5=0\)
Concept
For the first equation, (D=32-4(1)(5)=-11<0). A negative discriminant gives no real roots.
Why this answer is correct
The correct answer is A. \(x^2+3x+5=0\). For the first equation, (D=32-4(1)(5)=-11<0). A negative discriminant gives no real roots.
Exam Tip
पहले समीकरण में (D=32-4(1)(5)=-11<0) है। ऋणात्मक विविक्तकर वास्तविक मूल नहीं देता।
