Explanation opens after your attempt
Step 1
Concept
The sum of roots gives (s=17) and the product gives (p=72). Therefore (s+p=89).
Step 2
Why this answer is correct
The correct answer is A. (89). The sum of roots gives (s=17) and the product gives (p=72). Therefore (s+p=89).
Step 3
Exam Tip
मूलों का योग (s=17) और गुणनफल (p=72) है। इसलिए (s+p=89) है।

यदि \(x^2-Sx+P\) के शून्यक \(2\sqrt{3}+1\) और \(2\sqrt{3}-1\) हैं, तो (S) और (P) क्या हैं?
If the zeroes of \(x^2-Sx+P\) are \(2\sqrt{3}+1\) and \(2\sqrt{3}-1\), what are (S) and (P)?
#sum-product
#conjugate-form
#parameters
A \(S=4\sqrt{3}\), (P=11)
B \(S=2\sqrt{3}\), (P=11)
C \(S=4\sqrt{3}\), (P=13)
D (S=1), (P=12)
Explanation opens after your attempt
Correct Answer
A. \(S=4\sqrt{3}\), (P=11)
Step 1
Concept
The sum is \(4\sqrt{3}\) and the product is (\(2\sqrt{3}\)2 -1=11). (S) equals the sum and (P) equals the product.
Step 2
Why this answer is correct
The correct answer is A. \(S=4\sqrt{3}\), (P=11). The sum is \(4\sqrt{3}\) and the product is (\(2\sqrt{3}\)2 -1=11). (S) equals the sum and (P) equals the product.
Step 3
Exam Tip
योग \(4\sqrt{3}\) और गुणनफल (\(2\sqrt{3}\)2 -1=11) है। (S) योग और (P) गुणनफल के बराबर है।
