किस समीकरण का विवेचक (-11) है?
Which equation has discriminant (-11)?
Explanation opens after your attempt
A. \(x^2+x+3=0\)
Concept
For \(x^2+x+3=0\), \(D=1^2-4\cdot1\cdot3=-11\). Subtract the full (4ac) while finding the discriminant.
Why this answer is correct
The correct answer is A. \(x^2+x+3=0\). For \(x^2+x+3=0\), \(D=1^2-4\cdot1\cdot3=-11\). Subtract the full (4ac) while finding the discriminant.
Exam Tip
\(x^2+x+3=0\) के लिए \(D=1^2-4\cdot1\cdot3=-11\) है। विवेचक निकालते समय (4ac) पूरा घटाएं।
