यदि (x-2-(u+v+2)x+(u+1)(v+1)=0) की जड़ें समान हैं, तो सही कथन क्या है?
If (x-2-(u+v+2)x+(u+1)(v+1)=0) has equal roots, which statement is correct?
Explanation opens after your attempt
Correct Answer
C. (u=v)
Concept
The roots of this equation are (u+1) and (v+1). For equal roots, (u+1=v+1), so (u=v).
Why this answer is correct
The correct answer is C. (u=v). The roots of this equation are (u+1) and (v+1). For equal roots, (u+1=v+1), so (u=v).
Exam Tip
इस समीकरण की जड़ें (u+1) और (v+1) हैं। समान जड़ों के लिए (u+1=v+1), इसलिए (u=v)।
