समीकरण \(4x^2+x+6=0\) के विवेचक का चिन्ह क्या है?
What is the sign of the discriminant of \(4x^2+x+6=0\)?
Explanation opens after your attempt
C. ऋणात्मकNegative
Concept
\(D=1^2-4\cdot4\cdot6=1-96=-95\), so the discriminant is negative. Calculate (4ac) carefully.
Why this answer is correct
The correct answer is C. ऋणात्मक / Negative. \(D=1^2-4\cdot4\cdot6=1-96=-95\), so the discriminant is negative. Calculate (4ac) carefully.
Exam Tip
\(D=1^2-4\cdot4\cdot6=1-96=-95\), इसलिए विवेचक ऋणात्मक है। (4ac) की गणना सावधानी से करें।
