यदि \(\alpha\) और \(\beta\) समीकरण \(x^2-5x+6=0\) के मूल हैं तो \(\alpha+\beta+\alpha\beta\) का मान क्या है?
If \(\alpha\) and \(\beta\) are roots of \(x^2-5x+6=0\), what is the value of \(\alpha+\beta+\alpha\beta\)?
Explanation opens after your attempt
A. (11)
Concept
Here \(\alpha+\beta=5\) and \(\alpha\beta=6\). Therefore the total is (5+6=11).
Why this answer is correct
The correct answer is A. (11). Here \(\alpha+\beta=5\) and \(\alpha\beta=6\). Therefore the total is (5+6=11).
Exam Tip
यहां \(\alpha+\beta=5\) और \(\alpha\beta=6\) है। इसलिए कुल (5+6=11) है।
