यदि (p(x)=2x+7) और (q(x)=5x-3), तो (q(x)-p(x)) क्या है?

If (p(x)=2x+7) and (q(x)=5x-3), what is (q(x)-p(x))?

Explanation opens after your attempt
Correct Answer

B. (3x-10)

Explanation

Simple Explanation

घटाने पर (5x-2x=3x) और (-3-7=-10) मिलता है। इसलिए (q(x)-p(x)=3x-10) है। / On subtracting, (5x-2x=3x) and (-3-7=-10). Therefore (q(x)-p(x)=3x-10).

Question 148/150 Easy Mathematics Introduction to Polynomials Linear polynomials Class 9 Level 37

किस मान पर ((h-1)x+10) रेखीय बहुपद होगा?

For which value will ((h-1)x+10) be a linear polynomial?

Explanation opens after your attempt
Correct Answer

B. (h=0)

Explanation

Simple Explanation

(h=0) पर (x) का गुणांक (-1) है जो शून्य नहीं है। इसलिए बहुपद रेखीय है। / At (h=0), the coefficient of (x) is (-1), which is non-zero. Therefore the polynomial is linear.

Question 149/150 Easy Mathematics Introduction to Polynomials Linear polynomials Class 9 Level 37

यदि (p(x)=0\cdot x+14), तो (p(x)) की डिग्री क्या है?

If (p(x)=0\cdot x+14), what is the degree of (p(x))?

Explanation opens after your attempt
Correct Answer

C. (0)

Explanation

Simple Explanation

\(0\cdot x+14\) सरल होकर (14) बनता है। अशून्य नियतांक बहुपद की डिग्री (0) होती है। / \(0\cdot x+14\) simplifies to (14). A non-zero constant polynomial has degree (0).

Question 150/150 Easy Mathematics Introduction to Polynomials Linear polynomials Class 9 Level 37

रेखीय बहुपद (2x+10) का शून्यक क्या है?

What is the zero of the linear polynomial (2x+10)?

Explanation opens after your attempt
Correct Answer

B. (-5)

Explanation

Simple Explanation

(2x+10=0) से (x=-5) मिलता है। शून्यक निकालते समय चिन्ह का ध्यान रखें। / From (2x+10=0), we get (x=-5). Pay attention to the sign while finding the zero.
