निम्न में से किस बहुपद की घात (1) है?
Which polynomial has degree (1)?
Explanation opens after your attempt
Step 1
Concept
In (9x-3), the highest power of (x) is (1). So it is a polynomial of degree (1).
Step 2
Why this answer is correct
The correct answer is B. (9x-3). In (9x-3), the highest power of (x) is (1). So it is a polynomial of degree (1).
Step 3
Exam Tip
(9x-3) में (x) की सबसे बड़ी घात (1) है। इसलिए यह घात (1) का बहुपद है।

यदि (p(x)=3x-12) है, तो इसका शून्यक क्या है?
If (p(x)=3x-12), what is its zero?
Explanation opens after your attempt
Step 1
Concept
From (3x-12=0), we get (x=4). For a linear polynomial, form a simple equation.
Step 2
Why this answer is correct
The correct answer is B. (4). From (3x-12=0), we get (x=4). For a linear polynomial, form a simple equation.
Step 3
Exam Tip
(3x-12=0) से (x=4) मिलता है। रैखिक बहुपद में सीधे समीकरण बनाएं।

(9x+1) किस प्रकार का बहुपद है?
What type of polynomial is (9x+1)?
Explanation opens after your attempt
Correct Answer
B. रैखिक/Linear
Step 1
Concept
The highest power is (1), so it is a linear polynomial. If the power of (x) is (1), identify it as linear.
Step 2
Why this answer is correct
The correct answer is B. रैखिक / Linear. The highest power is (1), so it is a linear polynomial. If the power of (x) is (1), identify it as linear.
Step 3
Exam Tip
सबसे बड़ी घात (1) है इसलिए यह रैखिक बहुपद है। (x) की घात (1) दिखे तो रैखिक पहचानें।

कौन सा मान (p(x)=x+4) का शून्यक है?
Which value is a zero of (p(x)=x+4)?
Explanation opens after your attempt
Step 1
Concept
(p(-4)=-4+4=0), so (-4) is the zero. For (x+a), the zero is (-a).
Step 2
Why this answer is correct
The correct answer is B. (-4). (p(-4)=-4+4=0), so (-4) is the zero. For (x+a), the zero is (-a).
Step 3
Exam Tip
(p(-4)=-4+4=0), इसलिए (-4) शून्यक है। रैखिक बहुपद (x+a) का शून्यक (-a) होता है।

यदि (p(x)=4x) है तो ग्राफ और (x)-अक्ष का प्रतिच्छेद कौन सा है?
If (p(x)=4x), what is the intersection of the graph and the (x)-axis?
Explanation opens after your attempt
Correct Answer
A. ((0,0))
Step 1
Concept
Solving (4x=0) gives (x=0). So the graph cuts the (x)-axis at the origin.
Step 2
Why this answer is correct
The correct answer is A. ((0,0)). Solving (4x=0) gives (x=0). So the graph cuts the (x)-axis at the origin.
Step 3
Exam Tip
(4x=0) से (x=0) मिलता है। इसलिए ग्राफ मूल बिंदु पर (x)-अक्ष को काटता है।

यदि ग्राफ केवल (x= -6) पर (x)-अक्ष को काटता है और बाकी जगह अक्ष से दूर रहता है तो शून्यक क्या है?
If a graph cuts the (x)-axis only at (x=-6) and stays away from the axis elsewhere, what is the zero?
Explanation opens after your attempt
Step 1
Concept
Only at (x=-6) the value of (y) is (0). Hence the zero is (-6).
Step 2
Why this answer is correct
The correct answer is A. (-6). Only at (x=-6) the value of (y) is (0). Hence the zero is (-6).
Step 3
Exam Tip
केवल (x=-6) पर (y=0) है। इसलिए शून्यक (-6) है।
