किस व्यंजक में (x) का गुणांक (0) है लेकिन \(x^2\) का पद मौजूद है?
In which expression is the coefficient of (x) equal to (0) but the \(x^2\) term is present?
Explanation opens after your attempt
B. \(x^2-7\)
Concept
In \(x^2-7\), there is no first-power (x) term. So the coefficient of (x) is taken as (0).
Why this answer is correct
The correct answer is B. \(x^2-7\). In \(x^2-7\), there is no first-power (x) term. So the coefficient of (x) is taken as (0).
Exam Tip
\(x^2-7\) में प्रथम घात वाला (x) पद नहीं है। इसलिए (x) का गुणांक (0) माना जाता है।
