(x-2-(m+n)x+mn=0) के मूल कौनसे हैं?
What are the roots of (x-2-(m+n)x+mn=0)?
Explanation opens after your attempt
Correct Answer
A. (x=m,n)
Concept
The equation is equivalent to ((x-m)(x-n)=0), so the roots are (m) and (n). In exams, the same rule applies to symbolic factors.
Why this answer is correct
The correct answer is A. (x=m,n). The equation is equivalent to ((x-m)(x-n)=0), so the roots are (m) and (n). In exams, the same rule applies to symbolic factors.
Exam Tip
यह समीकरण ((x-m)(x-n)=0) के बराबर है, इसलिए मूल (m) और (n) हैं। परीक्षा में प्रतीकात्मक गुणनखंडों पर भी वही नियम लागू होता है।
