व्यंजक ((a-3)x-4+2x-2-5) की डिग्री (4) कब होगी?
When will the degree of ((a-3)x-4+2x-2-5) be (4)?
Explanation opens after your attempt
B. जब \(a\neq3\)When \(a\neq3\)
Concept
The degree remains (4) only when the coefficient of \(x^4\) is not zero. Hence \(a-3\neq0\).
Why this answer is correct
The correct answer is B. जब \(a\neq3\) / When \(a\neq3\). The degree remains (4) only when the coefficient of \(x^4\) is not zero. Hence \(a-3\neq0\).
Exam Tip
डिग्री (4) तभी रहेगी जब \(x^4\) का गुणांक शून्य न हो। इसलिए \(a-3\neq0\) होना चाहिए।
