किस मान के लिए (p(x)=x-2-10x+k) के शून्यक \(5+\sqrt{2}\) और \(5-\sqrt{2}\) होंगे?

For which value of (k) will (p(x)=x-2-10x+k) have zeroes \(5+\sqrt{2}\) and \(5-\sqrt{2}\)?

Explanation opens after your attempt
Correct Answer

A. (23)

Step 1

Concept

The product is (\(5+\sqrt{2}\)\(5-\sqrt{2}\)=25-2=23). So (k=23).

Step 2

Why this answer is correct

The correct answer is A. (23). The product is (\(5+\sqrt{2}\)\(5-\sqrt{2}\)=25-2=23). So (k=23).

Step 3

Exam Tip

गुणनफल (\(5+\sqrt{2}\)\(5-\sqrt{2}\)=25-2=23) है। इसलिए (k=23) होगा।
