यदि किसी द्विघात बहुपद के शून्यक \(4+\sqrt{7}\) और \(4-\sqrt{7}\) हैं, तो शून्यकों का गुणनफल क्या है?

If the zeroes of a quadratic polynomial are \(4+\sqrt{7}\) and \(4-\sqrt{7}\), what is their product?

Explanation opens after your attempt
Correct Answer

A. (9)

Step 1

Concept

The product is (\(4+\sqrt{7}\)\(4-\sqrt{7}\)=16-7=9). Use ((a+b)(a-b)=a-2-b-2) in exams.

Step 2

Why this answer is correct

The correct answer is A. (9). The product is (\(4+\sqrt{7}\)\(4-\sqrt{7}\)=16-7=9). Use ((a+b)(a-b)=a-2-b-2) in exams.

Step 3

Exam Tip

गुणनफल (\(4+\sqrt{7}\)\(4-\sqrt{7}\)=16-7=9) है। परीक्षा में ((a+b)(a-b)=a-2-b-2) लगाएं।
