समीकरण \(2x^2+5=0\) में कौन-सा पद अनुपस्थित है?
Which term is absent in \(2x^2+5=0\)?
#quadratic-equations
#missing-linear-term
#easy
A द्विघात पद / Quadratic term
B स्थिर पद / Constant term
C रैखिक पद / Linear term
D समीकरण चिह्न / Equation sign
Explanation opens after your attempt
Correct Answer
C. रैखिक पद / Linear term
Step 1
Concept
There is no (x) term, so the linear term is absent. The coefficient of a missing term is considered (0).
Step 2
Why this answer is correct
The correct answer is C. रैखिक पद / Linear term. There is no (x) term, so the linear term is absent. The coefficient of a missing term is considered (0).
Step 3
Exam Tip
इसमें (x) वाला पद नहीं है इसलिए रैखिक पद अनुपस्थित है। अनुपस्थित पद का गुणांक (0) माना जाता है।

Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
समीकरण ((k-1)x-2 +3x+2=0) द्विघात रहे इसके लिए कौन सी शर्त सही है?
Which condition is correct for ((k-1)x-2 +3x+2=0) to remain quadratic?
#quadratic equations
#parameter
#leading coefficient
A (k=1)
B \(k\neq1\)
C (k=0)
D (k=-1)
Explanation opens after your attempt
Correct Answer
B. \(k\neq1\)
Step 1
Concept
The coefficient of the quadratic term is ((k-1)), which must not be (0). Hence \(k\neq1\) is necessary.
Step 2
Why this answer is correct
The correct answer is B. \(k\neq1\). The coefficient of the quadratic term is ((k-1)), which must not be (0). Hence \(k\neq1\) is necessary.
Step 3
Exam Tip
द्विघात पद का गुणांक ((k-1)) है जो (0) नहीं होना चाहिए। इसलिए \(k\neq1\) होना जरूरी है।

समीकरण \(x^2-13x=0\) में कौन सा पद अनुपस्थित है?
Which term is absent in \(x^2-13x=0\)?
#quadratic equations
#missing term
#constant
A द्विघात पद / Quadratic term
B रैखिक पद / Linear term
C स्थिर पद / Constant term
D चर पद / Variable term
Explanation opens after your attempt
Correct Answer
C. स्थिर पद / Constant term
Step 1
Concept
It can be written as \(x^2-13x+0=0\). So the constant term is absent.
Step 2
Why this answer is correct
The correct answer is C. स्थिर पद / Constant term. It can be written as \(x^2-13x+0=0\). So the constant term is absent.
Step 3
Exam Tip
इसे \(x^2-13x+0=0\) लिखा जा सकता है। इसलिए स्थिर पद अनुपस्थित है।

Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
किस शर्त पर \(px^2+qx+r=0\) द्विघात समीकरण होगा?
Under which condition will \(px^2+qx+r=0\) be a quadratic equation?
#quadratic equations
#condition
#leading coefficient
A (p=0)
B \(p\neq0\)
C (q=0)
D (r=0)
Explanation opens after your attempt
Correct Answer
B. \(p\neq0\)
Step 1
Concept
The quadratic term \(px^2\) must remain, so \(p\neq0\). If (p=0), degree (2) will not remain.
Step 2
Why this answer is correct
The correct answer is B. \(p\neq0\). The quadratic term \(px^2\) must remain, so \(p\neq0\). If (p=0), degree (2) will not remain.
Step 3
Exam Tip
द्विघात पद \(px^2\) बना रहे इसलिए \(p\neq0\) होना चाहिए। यदि (p=0) हो तो घात (2) नहीं रहेगी।

Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28
किस शर्त पर \(ax^2+bx+c=0\) द्विघात समीकरण कहलाता है?
Under which condition is \(ax^2+bx+c=0\) called a quadratic equation?
#quadratic equations
#condition
#standard form
A (a=0)
B \(a\neq0\)
C (b=0)
D (c=0)
Explanation opens after your attempt
Correct Answer
B. \(a\neq0\)
Step 1
Concept
The quadratic term must remain, so \(a\neq0\). If (a=0), it may become linear.
Step 2
Why this answer is correct
The correct answer is B. \(a\neq0\). The quadratic term must remain, so \(a\neq0\). If (a=0), it may become linear.
