किस द्विघात समीकरण में मूलों का योग (-6) और गुणनफल (8) है?
Which quadratic equation has sum of roots (-6) and product (8)?
Explanation opens after your attempt
A. \(x^2+6x+8=0\)
Concept
\(A monic equation is (x^2-(\)sum)x+product\(=0). Substituting sum (-6) gives (x^2+6x+8=0).\)
Why this answer is correct
\(The correct answer is A. (x^2+6x+8=0). A monic equation is (x^2-(\)sum)x+product\(=0). Substituting sum (-6) gives (x^2+6x+8=0).\)
Exam Tip
\(मोनिक समीकरण (x^2-(\)योग)x+गुणनफल=0) होता है। \(योग (-6) रखने पर (x^2+6x+8=0) मिलता है\)।
