Question 38/50 Easy Mathematics Introduction to Polynomials Linear polynomials Class 9 Level 37

यदि (p(x)=0\cdot x-6), तो क्या यह रेखीय बहुपद है?

If (p(x)=0\cdot x-6), is it a linear polynomial?

Explanation opens after your attempt

Correct Answer

C. नहीं यह नियतांक बहुपद हैNo it is a constant polynomial

Step 1

Concept

\(0\cdot x-6\) simplifies to (-6). It is a constant polynomial, so it is not linear.

Step 2

Why this answer is correct

The correct answer is C. नहीं यह नियतांक बहुपद है / No it is a constant polynomial. \(0\cdot x-6\) simplifies to (-6). It is a constant polynomial, so it is not linear.

Step 3

Exam Tip

\(0\cdot x-6\) सरल होकर (-6) बनता है। यह नियतांक बहुपद है इसलिए रेखीय नहीं है।

किस मान पर ((r+11)x+4) रेखीय बहुपद नहीं रहेगा?

For which value will ((r+11)x+4) not remain a linear polynomial?

Explanation opens after your attempt

Correct Answer

C. (r=-11)

Step 1

Concept

To be linear, the coefficient of (x) must not be zero. At (r=-11), (r+11=0).

Step 2

Why this answer is correct

The correct answer is C. (r=-11). To be linear, the coefficient of (x) must not be zero. At (r=-11), (r+11=0).

Step 3

Exam Tip

रेखीय होने के लिए (x) का गुणांक शून्य नहीं होना चाहिए। (r=-11) पर (r+11=0) हो जाता है।

Explanation opens after your attempt

Correct Answer

A. (7x-7)

Step 1

Concept
