यदि \(A={x:x^2-5x+6=0}\) और \(B={x:x^2-4x+3=0}\) हैं, तो \(A\cap B\) क्या है?
If \(A={x:x^2-5x+6=0}\) and \(B={x:x^2-4x+3=0}\), what is \(A\cap B\)?
Explanation opens after your attempt
Correct Answer
A. ({3})
Concept
First \(A=\{2,3\}\) and \(B=\{1,3\}\), so the common element is ({3}). For equation-defined sets, find roots first.
Why this answer is correct
The correct answer is A. ({3}). First \(A=\{2,3\}\) and \(B=\{1,3\}\), so the common element is ({3}). For equation-defined sets, find roots first.
Exam Tip
पहले \(A=\{2,3\}\) और \(B=\{1,3\}\) मिलते हैं, इसलिए साझा तत्व ({3}) है। समीकरण वाले समुच्चय में पहले मूल निकालें।
