समीकरण \(x^2-14x+49=0\) के मूलों का योग और गुणनफल क्रमशः क्या हैं?

For \(x^2-14x+49=0\), what are the sum and product of roots respectively?

Explanation opens after your attempt
Correct Answer

A. (14) और (49)(14) and (49)

Step 1

Concept

It is ((x-7)2=0), so both roots are (7). The sum is (14) and the product is (49).

Step 2

Why this answer is correct

The correct answer is A. (14) और (49) / (14) and (49). It is ((x-7)2=0), so both roots are (7). The sum is (14) and the product is (49).

Step 3

Exam Tip

यह ((x-7)2=0) है इसलिए दोनों मूल (7) हैं। योग (14) और गुणनफल (49) होगा।
