कौन-सा व्यंजक बहुपद है लेकिन उसमें लगातार सभी घातें नहीं आतीं?
Which expression is a polynomial but does not contain all consecutive powers?
Explanation opens after your attempt
A. \(x^5+2x^2-3\)
Concept
A polynomial need not contain all middle powers. In \(x^5+2x^2-3\), the present powers (5), (2), (0) are valid.
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.
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।
