If (p(x)=(a-5)x^6+4x^2-9) is to be exactly a quadratic polynomial, what is the value of (a)?यदि (p(x)=(a-5)x^6+4x^2-9) को ठीक द्विघात बहुपद बनाना हो, तो (a) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (5)(5)
For exactly quadratic, the coefficient of (x^6) must be zero and the coefficient of (x^2) is non-zero. From (a-5=0), (a=5).ठीक द्विघात के लिए (x^6) का गुणांक शून्य होना चाहिए और (x^2) का गुणांक अशून्य है। (a-5=0) से (a=5) मिलता है।
