निम्न में से शुद्ध द्विघात समीकरण कौन-सा है?
Which of the following is a pure quadratic equation?
Explanation opens after your attempt
Correct Answer
C. \(4x^2-9=0\)
Step 1
Concept
A pure quadratic equation has no (x) term. In \(4x^2-9=0\), the linear term is absent.
Step 2
Why this answer is correct
The correct answer is C. \(4x^2-9=0\). A pure quadratic equation has no (x) term. In \(4x^2-9=0\), the linear term is absent.
Step 3
Exam Tip
शुद्ध द्विघात में (x) वाला पद नहीं होता है। \(4x^2-9=0\) में रैखिक पद अनुपस्थित है।

Question
Medium Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28
किस समीकरण के दोनों मूल विपरीत संख्याएँ होंगे?
Which equation will have roots that are opposite numbers?
Explanation opens after your attempt
Correct Answer
A. \(x^2-16=0\)
Step 1
Concept
\(x^2-16=0\) gives \(x=\pm4\), which are opposite numbers. Pure quadratics often give opposite roots.
Step 2
Why this answer is correct
The correct answer is A. \(x^2-16=0\). \(x^2-16=0\) gives \(x=\pm4\), which are opposite numbers. Pure quadratics often give opposite roots.
Step 3
Exam Tip
\(x^2-16=0\) से \(x=\pm4\) मिलता है, जो विपरीत संख्याएँ हैं। शुद्ध द्विघात में अक्सर विपरीत मूल मिलते हैं।

Question
Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
समीकरण \(12x^2=0\) के लिए (a), (b), (c) क्रमशः क्या हैं?
For \(12x^2=0\), what are (a), (b), (c) respectively?
Explanation opens after your attempt
Correct Answer
A. (12,0,0)
Step 1
Concept
It is written as \(12x^2+0x+0=0\). Therefore (a=12), (b=0), (c=0).
Step 2
Why this answer is correct
The correct answer is A. (12,0,0). It is written as \(12x^2+0x+0=0\). Therefore (a=12), (b=0), (c=0).
Step 3
Exam Tip
इसे \(12x^2+0x+0=0\) लिखा जाता है। इसलिए (a=12), (b=0), (c=0) हैं।
