यदि \(\alpha\) और \(\beta\) समीकरण \(x^2-9x+20=0\) के मूल हैं तो \(\alpha+\beta+\alpha\beta\) का मान क्या है?

If \(\alpha\) and \(\beta\) are roots of \(x^2-9x+20=0\), what is the value of \(\alpha+\beta+\alpha\beta\)?

Explanation opens after your attempt
Correct Answer

A. (29)

Step 1

Concept

Here \(\alpha+\beta=9\) and \(\alpha\beta=20\). Therefore the total is (9+20=29).

Step 2

Why this answer is correct

The correct answer is A. (29). Here \(\alpha+\beta=9\) and \(\alpha\beta=20\). Therefore the total is (9+20=29).

Step 3

Exam Tip

यहां \(\alpha+\beta=9\) और \(\alpha\beta=20\) है। इसलिए कुल (9+20=29) है।
