Which expression is a polynomial in (x) and does not have an \(x^2\) term?
Explanation opens after your attempt
A. \(x^4+3x-5\)
Concept
A polynomial need not contain every power term. In \(x^4+3x-5\), the present powers are valid.
Why this answer is correct
The correct answer is A. \(x^4+3x-5\). A polynomial need not contain every power term. In \(x^4+3x-5\), the present powers are valid.
Exam Tip
बहुपद में हर घात का पद होना जरूरी नहीं है। \(x^4+3x-5\) में उपस्थित घातें मान्य हैं।
