किस मान पर ((2a-8)x-6+(a+1)x-3+4) की डिग्री (3) होगी?
For which value will the degree of ((2a-8)x-6+(a+1)x-3+4) be (3)?
Explanation opens after your attempt
C. (a=4)
Concept
For degree (3), the coefficient of \(x^6\) must be (0) and the coefficient of \(x^3\) must remain non-zero. From (2a-8=0), (a=4).
Why this answer is correct
The correct answer is C. (a=4). For degree (3), the coefficient of \(x^6\) must be (0) and the coefficient of \(x^3\) must remain non-zero. From (2a-8=0), (a=4).
Exam Tip
डिग्री (3) के लिए \(x^6\) का गुणांक (0) होना चाहिए और \(x^3\) का गुणांक अशून्य रहना चाहिए। (2a-8=0) से (a=4) मिलता है।
