यदि \(\alpha+\beta=6\) और \(\alpha\beta=8\), तो शून्यक \(\alpha+1\) और \(\beta+1\) वाला मोनिक बहुपद कौन-सा है?
If \(\alpha+\beta=6\) and \(\alpha\beta=8\), which monic polynomial has zeroes \(\alpha+1\) and \(\beta+1\)?
Explanation opens after your attempt
A. \(x^2-8x+15\)
Concept
The new sum is \(\alpha+\beta+2=8\) and product is \(\alpha\beta+\alpha+\beta+1=15\). Thus the polynomial is \(x^2-8x+15\).
Why this answer is correct
The correct answer is A. \(x^2-8x+15\). The new sum is \(\alpha+\beta+2=8\) and product is \(\alpha\beta+\alpha+\beta+1=15\). Thus the polynomial is \(x^2-8x+15\).
Exam Tip
नए शून्यकों का योग \(\alpha+\beta+2=8\) और गुणनफल \(\alpha\beta+\alpha+\beta+1=15\) है। अतः बहुपद \(x^2-8x+15\) है।
