Correct Answer

A. \(x^5+2x^2-3\)

Step 1

Concept

A polynomial need not contain all middle powers. In \(x^5+2x^2-3\), the present powers (5), (2), (0) are valid.

Step 2

Why this answer is correct

The correct answer is A. \(x^5+2x^2-3\). A polynomial need not contain all middle powers. In \(x^5+2x^2-3\), the present powers (5), (2), (0) are valid.

Step 3

Exam Tip

बहुपद में बीच की घातों का होना जरूरी नहीं है। \(x^5+2x^2-3\) में उपस्थित घातें (5), (2), (0) हैं और मान्य हैं।
