यदि (p(x)=\lambda x+10) और इसका शून्यक (-2) से छोटा है, तो \(\lambda>0\) होने पर कौन सी शर्त सही है?
If (p(x)=\lambda x+10) and its zero is less than (-2), which condition is correct when \(\lambda>0\)?
Explanation opens after your attempt
Correct Answer
A. \(0<\lambda<5\)
Concept
The zero is \(-\frac{10}{\lambda}\). From \(-\frac{10}{\lambda}<-2\) and \(\lambda>0\), we get \(0<\lambda<5\).
Why this answer is correct
The correct answer is A. \(0<\lambda<5\). The zero is \(-\frac{10}{\lambda}\). From \(-\frac{10}{\lambda}<-2\) and \(\lambda>0\), we get \(0<\lambda<5\).
Exam Tip
शून्यक \(-\frac{10}{\lambda}\) है। \(-\frac{10}{\lambda}<-2\) और \(\lambda>0\) से \(0<\lambda<5\) मिलता है।
