घात (4) के लिए \(x^5\) का गुणांक शून्य और \(x^4\) का गुणांक अशून्य चाहिए। (m=-4) पर (m-1=-5) अशून्य है। / For degree (4), the \(x^5\) coefficient must be zero and the \(x^4\) coefficient must be non-zero. At (m=-4), (m-1=-5) is non-zero.
Mathematics Answer, Explanation and Revision Hints
यदि (q(x)=(m+4)x-5+(m-1)x-4+x-2) की घात (4) हो, तो (m) क्या होगा? / If (q(x)=(m+4)x-5+(m-1)x-4+x-2) has degree (4), what is (m)?
Correct Answer: B. (-4). Explanation: घात (4) के लिए \(x^5\) का गुणांक शून्य और \(x^4\) का गुणांक अशून्य चाहिए। (m=-4) पर (m-1=-5) अशून्य है। / For degree (4), the \(x^5\) coefficient must be zero and the \(x^4\) coefficient must be non-zero. At (m=-4), (m-1=-5) is non-zero.
