If s = −1, what is the degree of (s + 1)x⁵ + (s + 4)x² + 8?यदि s = −1 हो, तो (s + 1)x⁵ + (s + 4)x² + 8 की डिग्री क्या होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 22
Put s = −1 into the coefficients. Then s + 1 = 0, so the x⁵ term vanishes, while s + 4 = 3, so the x² term becomes 3x². The polynomial is therefore 3x² + 8. Its highest remaining power with a non-zero coefficient is 2, hence its degree is 2. The original x⁵ term cannot determine the degree after its coefficient becomes zero.s = −1 रखने पर s + 1 = 0 होता है, इसलिए x⁵ वाला पद समाप्त हो जाता है। साथ ही s + 4 = 3, अतः x² वाला पद 3x² बनता है। पूरा बहुपद 3x² + 8 रह जाता है। इसमें अशून्य गुणांक वाली सबसे बड़ी घात 2 है, इसलिए डिग्री 2 होगी। मूल x⁵ पद का गुणांक शून्य हो जाने के कारण वह डिग्री निर्धारित नहीं कर सकता।
