यदि (p(x)=(a-5)x-6+4x-2-9) को ठीक द्विघात बहुपद बनाना हो, तो (a) का मान क्या होगा?
If (p(x)=(a-5)x-6+4x-2-9) is to be exactly a quadratic polynomial, what is the value of (a)?
Explanation opens after your attempt
Correct Answer
A. (5)
Concept
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).
Why this answer is correct
The correct answer is A. (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).
Exam Tip
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।
