व्यंजक ((u-5)x-3+(u-5)x-2+7) नियतांक बहुपद कब बनेगा?
When will ((u-5)x-3+(u-5)x-2+7) become a constant polynomial?
Explanation opens after your attempt
Correct Answer
A. जब (u=5)When (u=5)
Concept
To become constant, the coefficients of both \(x^3\) and \(x^2\) must be (0). From (u-5=0), both terms disappear.
Why this answer is correct
The correct answer is A. जब (u=5) / When (u=5). To become constant, the coefficients of both \(x^3\) and \(x^2\) must be (0). From (u-5=0), both terms disappear.
Exam Tip
नियतांक बनने के लिए \(x^3\) और \(x^2\) दोनों के गुणांक (0) चाहिए। (u-5=0) से दोनों पद हट जाते हैं।
