कौन-सा व्यंजक (x) में बहुपद है यदि (k) को स्थिर माना जाए?
Which expression is a polynomial in (x) if (k) is treated as a constant?
Explanation opens after your attempt
A. \(kx^3-2x+8\)
Concept
(k) acts like a constant coefficient. The powers of (x) are (3), (1), and (0), so it is a polynomial.
Why this answer is correct
The correct answer is A. \(kx^3-2x+8\). (k) acts like a constant coefficient. The powers of (x) are (3), (1), and (0), so it is a polynomial.
Exam Tip
(k) स्थिर की तरह गुणांक है। (x) की घातें (3), (1) और (0) हैं इसलिए यह बहुपद है।
