Question 1/4 Expert Mathematics Introduction to Polynomials Definition of polynomial Class 9 Level 28

कौन-सा व्यंजक (x) में बहुपद है, जबकि (z) गुणांक की तरह काम करता है?

Which expression is a polynomial in (x), while (z) acts like a coefficient?

Explanation opens after your attempt
Correct Answer

B. \(z^2x^4+3zx^2-8\)

Step 1

Concept

With respect to (x), \(z^2\) and (3z) are coefficients. The powers of (x) are (4), (2), and (0).

Step 2

Why this answer is correct

The correct answer is B. \(z^2x^4+3zx^2-8\). With respect to (x), \(z^2\) and (3z) are coefficients. The powers of (x) are (4), (2), and (0).

Step 3

Exam Tip

(x) के संदर्भ में \(z^2\) और (3z) गुणांक हैं। (x) की घातें (4), (2) और (0) हैं।

Question 2/4 Expert Mathematics Introduction to Polynomials Definition of polynomial Class 9 Level 26

कौन-सा व्यंजक (u) में बहुपद है लेकिन (x) को गुणांक की तरह रखता है?

Which expression is a polynomial in (u) but keeps (x) like a coefficient?

Explanation opens after your attempt
Correct Answer

A. \(xu^3-4u+2\)

Step 1

Concept

With respect to (u), (x) can be treated like a coefficient. The powers of (u) are (3), (1), and (0).

Step 2

Why this answer is correct

The correct answer is A. \(xu^3-4u+2\). With respect to (u), (x) can be treated like a coefficient. The powers of (u) are (3), (1), and (0).

Step 3

Exam Tip

(u) के संदर्भ में (x) गुणांक की तरह माना जा सकता है। (u) की घातें (3), (1) और (0) हैं।
