यदि (p(x)=ax-4+3x-2-1) में (a=0) हो, तो घात क्या होगी?
If (a=0) in (p(x)=ax-4+3x-2-1), what will be the degree?
Explanation opens after your attempt
C. (2)
Concept
When (a=0), the \(x^4\) term disappears. The remaining polynomial \(3x^2-1\) has degree (2).
Why this answer is correct
The correct answer is C. (2). When (a=0), the \(x^4\) term disappears. The remaining polynomial \(3x^2-1\) has degree (2).
Exam Tip
(a=0) होने पर \(x^4\) वाला पद हट जाता है। शेष बहुपद \(3x^2-1\) की घात (2) है।
