यदि (p(x)=ax-5+3x-2-7) में (a=0) हो, तो (p(x)) की घात क्या होगी?
If (a=0) in (p(x)=ax-5+3x-2-7), what will be the degree of (p(x))?
Explanation opens after your attempt
B. (2)
Concept
When (a=0), the \(x^5\) term disappears. The highest remaining term is \(3x^2\).
Why this answer is correct
The correct answer is B. (2). When (a=0), the \(x^5\) term disappears. The highest remaining term is \(3x^2\).
Exam Tip
(a=0) होने पर \(x^5\) वाला पद हट जाता है। बचा हुआ सबसे बड़ा पद \(3x^2\) है।
