किस द्विघात समीकरण के मूलों का योग (0) और गुणनफल (-49) है?
Which quadratic equation has sum of roots (0) and product (-49)?
Explanation opens after your attempt
Correct Answer
A. \(x^2-49=0\)
Concept
\(The monic equation is (x^2-(\)sum)x+product\(=0). Using sum (0) and product (-49) gives (x^2-49=0).\)
Why this answer is correct
\(The correct answer is A. (x^2-49=0). The monic equation is (x^2-(\)sum)x+product\(=0). Using sum (0) and product (-49) gives (x^2-49=0).\)
Exam Tip
\(मोनिक समीकरण (x^2-(\)योग)x+गुणनफल=0) है। \(योग (0) और गुणनफल (-49) रखने पर (x^2-49=0) मिलता है\)।
