यदि किसी बहुपद का ग्राफ (x)-अक्ष को (x=-2), (x=0) और (x=3) पर काटता है, तो सबसे कम घात का मोनिक बहुपद कौन-सा है?
If the graph of a polynomial cuts the (x)-axis at (x=-2), (x=0), and (x=3), which is the monic polynomial of least degree?
#graph-zeroes
#least-degree
#polynomial
A \(x^3-x^2-6x\)
B \(x^3+x^2-6x\)
C \(x^3-6x\)
D \(x^3+6x^2-x\)
Explanation opens after your attempt
Correct Answer
A. \(x^3-x^2-6x\)
Step 1
Concept
The zeroes are (-2,0,3), so the polynomial is (x(x+2)(x-3)=x-3 -x-2 -6x). Intersections with the (x)-axis give zeroes.
Step 2
Why this answer is correct
The correct answer is A. \(x^3-x^2-6x\). The zeroes are (-2,0,3), so the polynomial is (x(x+2)(x-3)=x-3 -x-2 -6x). Intersections with the (x)-axis give zeroes.
Step 3
Exam Tip
शून्यक (-2,0,3) हैं, इसलिए बहुपद (x(x+2)(x-3)=x-3 -x-2 -6x) है। (x)-अक्ष काटने के बिंदु शून्यक बताते हैं।

(9) किस प्रकार का बहुपद है?
What type of polynomial is (9)?
#constant-polynomial
#degree-zero
A रैखिक बहुपद / Linear polynomial
B द्विघात बहुपद / Quadratic polynomial
C नियत बहुपद / Constant polynomial
D त्रिघात बहुपद / Cubic polynomial
Explanation opens after your attempt
Correct Answer
C. नियत बहुपद / Constant polynomial
Step 1
Concept
(9) has no variable, so it is a constant polynomial. A non-zero constant polynomial has degree (0).
Step 2
Why this answer is correct
The correct answer is C. नियत बहुपद / Constant polynomial. (9) has no variable, so it is a constant polynomial. A non-zero constant polynomial has degree (0).
Step 3
Exam Tip
(9) में चर नहीं है इसलिए यह नियत बहुपद है। गैर-शून्य नियत बहुपद की घात (0) होती है।

(p(x)=ax-2 +bx+c) में यदि \(a\ne0\) है, तो यह किस प्रकार का बहुपद है?
In (p(x)=ax-2 +bx+c), if \(a\ne0\), what type of polynomial is it?
#polynomials
#quadratic-form
#easy
#degree
A रैखिक / Linear
B द्विघात / Quadratic
C घन / Cubic
D नियत / Constant
Explanation opens after your attempt
Correct Answer
B. द्विघात / Quadratic
Step 1
Concept
Since \(a\ne0\), the \(x^2\)-term remains, so the degree is (2). A degree (2) polynomial is quadratic.
Step 2
Why this answer is correct
The correct answer is B. द्विघात / Quadratic. Since \(a\ne0\), the \(x^2\)-term remains, so the degree is (2). A degree (2) polynomial is quadratic.
Step 3
Exam Tip
\(a\ne0\) होने से \(x^2\) पद रहता है, इसलिए घात (2) है। घात (2) वाला बहुपद द्विघात होता है।

यदि (p(x)=ax-2 +bx+c) और \(a\neq0\), तो (p(x)) किस प्रकार का बहुपद है?
If (p(x)=ax-2 +bx+c) and \(a\neq0\), what type of polynomial is (p(x))?
#quadratic_form
#degree
#classification
A रैखिक / Linear
B द्विघात / Quadratic
C घन / Cubic
D स्थिर / Constant
Explanation opens after your attempt
Correct Answer
B. द्विघात / Quadratic
Step 1
Concept
Since \(a\neq0\), the \(x^2\) term is present. So the degree is (2) and it is a quadratic polynomial.
Step 2
Why this answer is correct
The correct answer is B. द्विघात / Quadratic. Since \(a\neq0\), the \(x^2\) term is present. So the degree is (2) and it is a quadratic polynomial.
Step 3
Exam Tip
क्योंकि \(a\neq0\), \(x^2\) वाला पद उपस्थित है। इसलिए घात (2) है और यह द्विघात बहुपद है।
