यदि (a=5), (b=-11), (c=-6) हैं, तो संबंधित द्विघात समीकरण कौन-सा है?
If (a=5), (b=-11), (c=-6), which is the corresponding quadratic equation?
Explanation opens after your attempt
Correct Answer
B. \(5x^2-11x-6=0\)
Concept
Substituting into \(ax^2+bx+c=0\) gives \(5x^2-11x-6=0\). Treat the negative sign as part of the coefficient.
Why this answer is correct
The correct answer is B. \(5x^2-11x-6=0\). Substituting into \(ax^2+bx+c=0\) gives \(5x^2-11x-6=0\). Treat the negative sign as part of the coefficient.
Exam Tip
मानक रूप \(ax^2+bx+c=0\) में मान रखने पर \(5x^2-11x-6=0\) मिलता है। ऋण चिन्ह को गुणांक का भाग मानें।
