समीकरण \(3x^2-6x+3=0\) का डिस्क्रिमिनेंट (D) क्या है?
What is the discriminant (D) of \(3x^2-6x+3=0\)?
Explanation opens after your attempt
A. (0)
Concept
Here \(D=b^2-4ac=36-36=0\). Therefore the two real roots will be equal.
Why this answer is correct
The correct answer is A. (0). Here \(D=b^2-4ac=36-36=0\). Therefore the two real roots will be equal.
Exam Tip
यहां \(D=b^2-4ac=36-36=0\) है। इसलिए दोनों वास्तविक मूल बराबर होंगे।
