यदि (h=1), तो ((h-1)x-6+(h+2)x-3-4x+9) की डिग्री क्या होगी?
If (h=1), what will be the degree of ((h-1)x-6+(h+2)x-3-4x+9)?
Explanation opens after your attempt
B. (3)
Concept
Putting (h=1) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (3).
Why this answer is correct
The correct answer is B. (3). Putting (h=1) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (3).
Exam Tip
(h=1) रखने पर \(x^6\) का गुणांक (0) हो जाता है। बची हुई सबसे बड़ी घात (3) है।
