Which statement is correct about \(3a^2b\) and \(5ab^2\)?
C. दोनों असमान पद हैंBoth are unlike terms
चर समान दिखते हैं पर उनकी घातें अलग हैं। समान पदों में चर और घात दोनों समान होने चाहिए। / The variables look similar but their powers are different. Like terms must have the same variables with the same powers.

What is obtained after simplifying (6p-4q+2p+9q)?
A. (8p+5q)
समान पदों को जोड़ें तो (6p+2p=8p) और (-4q+9q=5q)। पहले समान चर वाले पदों को समूहित करें। / Combining like terms gives (6p+2p=8p) and (-4q+9q=5q). Group terms with the same variable first.

If (x=-2), what is the value of \(x^2+3x+1\)?
D. (-1)
मान रखने पर ((-2)2+3(-2)+1=4-6+1=-1)। ऋणात्मक संख्या का वर्ग करते समय कोष्ठक लगाएँ। / Substitution gives ((-2)2+3(-2)+1=4-6+1=-1). Use brackets when squaring a negative number.

Which expression is obtained after simplifying (2(x-5)+3x)?
C. (5x-10)
पहले (2(x-5)=2x-10) करें फिर (3x) जोड़ें। इससे (5x-10) मिलता है। / First expand (2(x-5)=2x-10), then add (3x). This gives (5x-10).

Which option correctly gives the coefficient of (x) in \(4x^2-3x+6\)?
B. (-3)
(x) वाला पद (-3x) है। इसलिए (x) का गुणांक (-3) है। / The term containing (x) is (-3x). So the coefficient of (x) is (-3).

If (a=2) and (b=-1), what is the value of (3a-2b)?
C. (8)
(3a-2b=3(2)-2(-1)=6+2=8)। ऋणात्मक मान घटाने पर जोड़ बन सकता है। / (3a-2b=3(2)-2(-1)=6+2=8). Subtracting a negative value can become addition.

Which expression represents three times the sum of (m) and (n)?
C. (3(m+n))
योग पहले लेना है और फिर उसे (3) से गुणा करना है। इसलिए कोष्ठक वाला रूप (3(m+n)) सही है। / The sum must be taken first and then multiplied by (3). So the bracketed form (3(m+n)) is correct.
