\(x^2+3x+2=0\) के मूल क्या होंगे?
What are the roots of \(x^2+3x+2=0\)?
Explanation opens after your attempt
A. (x=-1,-2)
Concept
((x+1)(x+2)=0), so (x=-1) and (x=-2). In exams, from ((x+a)=0), write (x=-a).
Why this answer is correct
The correct answer is A. (x=-1,-2). ((x+1)(x+2)=0), so (x=-1) and (x=-2). In exams, from ((x+a)=0), write (x=-a).
Exam Tip
((x+1)(x+2)=0), इसलिए (x=-1) और (x=-2) हैं। परीक्षा में ((x+a)=0) से (x=-a) लिखें।
