कौन-सा व्यंजक (x) में बहुपद है यदि (a) को स्थिर माना जाए?
Which expression is a polynomial in (x) if (a) is treated as a constant?
Explanation opens after your attempt
A. \(ax^2+3x-1\)
Concept
Treating (a) as a constant, \(ax^2\) has (x)-power (2). All powers of (x) are non-negative integers.
Why this answer is correct
The correct answer is A. \(ax^2+3x-1\). Treating (a) as a constant, \(ax^2\) has (x)-power (2). All powers of (x) are non-negative integers.
Exam Tip
(a) को स्थिर मानने पर \(ax^2\) में (x) की घात (2) है। सभी (x) घातें शून्य या धनात्मक पूर्णांक हैं।
