यदि (p(x)=x-2+px+q) के शून्यक \(7+\sqrt{13}\) और \(7-\sqrt{13}\) हैं, तो (p+q) क्या है?
If zeroes of (p(x)=x-2+px+q) are \(7+\sqrt{13}\) and \(7-\sqrt{13}\), what is (p+q)?
Explanation opens after your attempt
A. (22)
Concept
The sum is (14), so (p=-14). The product is (49-13=36), so (q=36) and (p+q=22).
Why this answer is correct
The correct answer is A. (22). The sum is (14), so (p=-14). The product is (49-13=36), so (q=36) and (p+q=22).
Exam Tip
योग (14) है, इसलिए (p=-14)। गुणनफल (49-13=36) है, इसलिए (q=36) और (p+q=22)।
