\(x^2+2x+1\) में \(x^2\) का गुणांक क्या है?
What is the coefficient of \(x^2\) in \(x^2+2x+1\)?
Explanation opens after your attempt
C. (1)
Concept
No number is written before \(x^2\), so its coefficient is (1). Treat the invisible coefficient as (1).
Why this answer is correct
The correct answer is C. (1). No number is written before \(x^2\), so its coefficient is (1). Treat the invisible coefficient as (1).
Exam Tip
\(x^2\) के आगे कोई संख्या नहीं लिखी है इसलिए गुणांक (1) होता है। अदृश्य गुणांक को (1) मानें।
