किस समीकरण का विवेचक (-23) है?
Which equation has discriminant (-23)?
Explanation opens after your attempt
A. \(x^2+x+6=0\)
Concept
For \(x^2+x+6=0\), \(D=1^2-4\cdot1\cdot6=-23\). Subtract the full (4ac) in the discriminant.
Why this answer is correct
The correct answer is A. \(x^2+x+6=0\). For \(x^2+x+6=0\), \(D=1^2-4\cdot1\cdot6=-23\). Subtract the full (4ac) in the discriminant.
Exam Tip
\(x^2+x+6=0\) के लिए \(D=1^2-4\cdot1\cdot6=-23\) है। विवेचक में (4ac) पूरा घटाएं।
