यदि \(x^2-5x+4=0\) के मूल \(\alpha\) और \(\beta\) हैं तो \(\alpha+2\) और \(\beta+2\) का योग क्या होगा?
If \(\alpha\) and \(\beta\) are roots of \(x^2-5x+4=0\), what is the sum of \(\alpha+2\) and \(\beta+2\)?
Explanation opens after your attempt
A. (9)
Concept
The old sum of roots is (5). The new sum is (\(\alpha+2\)+\(\beta+2\)=\alpha+\beta+4=9).
Why this answer is correct
The correct answer is A. (9). The old sum of roots is (5). The new sum is (\(\alpha+2\)+\(\beta+2\)=\alpha+\beta+4=9).
Exam Tip
पुराने मूलों का योग (5) है। नए योग (\(\alpha+2\)+\(\beta+2\)=\alpha+\beta+4=9) होगा।
