C \(\sqrt{x}+4\)
D \(x^{-2}+3\)
Explanation opens after your attempt
Correct Answer
B. \(3x^2-5x+1\)
Step 1
Concept
In a polynomial, powers of the variable must be whole numbers including zero. In \(3x^2-5x+1\), the powers are (2), (1), and (0).
Step 2
Why this answer is correct
The correct answer is B. \(3x^2-5x+1\). In a polynomial, powers of the variable must be whole numbers including zero. In \(3x^2-5x+1\), the powers are (2), (1), and (0).
Step 3
Exam Tip
बहुपद में चर की घात पूर्ण अशून्य या शून्य संख्या होनी चाहिए। \(3x^2-5x+1\) में घातें (2), (1), और (0) हैं।
