Question 1/4 Easy Mathematics Introduction to Polynomials Definition of polynomial Class 9 Level 31

क्या \(0.25x^2-5x+3\) (x) में बहुपद है?

Is \(0.25x^2-5x+3\) a polynomial in (x)?

Explanation opens after your attempt
Correct Answer

A. हां, क्योंकि दशमलव गुणांक वास्तविक संख्या हैYes, because a decimal coefficient is a real number

Step 1

Concept

A decimal coefficient is a real number and the powers of (x) are (2), (1), and (0). Therefore it is a polynomial.

Step 2

Why this answer is correct

The correct answer is A. हां, क्योंकि दशमलव गुणांक वास्तविक संख्या है / Yes, because a decimal coefficient is a real number. A decimal coefficient is a real number and the powers of (x) are (2), (1), and (0). Therefore it is a polynomial.

Step 3

Exam Tip

दशमलव गुणांक वास्तविक संख्या होता है और (x) की घातें (2), (1), और (0) हैं। इसलिए यह बहुपद है।

Question 2/4 Medium Mathematics Introduction to Polynomials Definition of polynomial Class 9 Level 27

कौन-सा व्यंजक (x) में बहुपद है और दशमलव गुणांक रखता है?

Which expression is a polynomial in (x) with a decimal coefficient?

Explanation opens after your attempt
Correct Answer

A. \(1.5x^2-4x+3\)

Step 1

Concept

The decimal (1.5) is a real coefficient. The powers of (x) are (2), (1), and (0), which are valid.

Step 2

Why this answer is correct

The correct answer is A. \(1.5x^2-4x+3\). The decimal (1.5) is a real coefficient. The powers of (x) are (2), (1), and (0), which are valid.

Step 3

Exam Tip

दशमलव (1.5) वास्तविक गुणांक है। (x) की घातें (2), (1) और (0) मान्य हैं।

Question 3/4 Easy Mathematics Introduction to Polynomials Definition of polynomial Class 9 Level 30

व्यंजक \(0.5x^2+3x-1\) (x) में बहुपद है या नहीं?

Is \(0.5x^2+3x-1\) a polynomial in (x)?

Explanation opens after your attempt
Correct Answer

A. हां, क्योंकि दशमलव गुणांक भी वास्तविक संख्या हैYes, because a decimal coefficient is also a real number

Step 1

Concept

Coefficients in a polynomial can be real numbers. Here the powers of (x) are (2), (1), and (0).

Step 2

Why this answer is correct

The correct answer is A. हां, क्योंकि दशमलव गुणांक भी वास्तविक संख्या है / Yes, because a decimal coefficient is also a real number. Coefficients in a polynomial can be real numbers. Here the powers of (x) are (2), (1), and (0).

Step 3

Exam Tip

बहुपद में गुणांक वास्तविक संख्या हो सकते हैं। यहां (x) की घातें (2), (1), और (0) हैं।

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

कौन-सा व्यंजक वास्तविक गुणांक वाला बहुपद है?

Which expression is a polynomial with real coefficients?

Explanation opens after your attempt
Correct Answer

A. \(2.5x^2-3x+1\)

Step 1

Concept

The decimal (2.5) is also a real coefficient. All powers of the variable are non-negative integers.

Step 2

Why this answer is correct

The correct answer is A. \(2.5x^2-3x+1\). The decimal (2.5) is also a real coefficient. All powers of the variable are non-negative integers.

Step 3

Exam Tip

दशमलव (2.5) भी वास्तविक गुणांक है। चर की सभी घातें शून्य या धनात्मक पूर्णांक हैं।
