यदि (p(x)=\lambda x-4-2x-2+3) की घात (4) है, तो \(\lambda\) के लिए कौन-सी शर्त सही है?
If (p(x)=\lambda x-4-2x-2+3) has degree (4), which condition is correct for \(\lambda\)?
Explanation opens after your attempt
B. \(\lambda\neq0\)
Concept
The degree is (4) only when the coefficient of \(x^4\) is not zero. Therefore, \(\lambda\neq0\) is required.
Why this answer is correct
The correct answer is B. \(\lambda\neq0\). The degree is (4) only when the coefficient of \(x^4\) is not zero. Therefore, \(\lambda\neq0\) is required.
Exam Tip
घात (4) तभी होगी जब \(x^4\) का गुणांक शून्य न हो। इसलिए \(\lambda\neq0\) आवश्यक है।
