Medium Mathematics Quadratic Equations Class 10 Level 29

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
Correct Answer

A. \(x^2+6x+8=0\)

Step 1

Concept

\(A monic equation is (x^2-(\)sum)x+product\(=0). Substituting sum (-6) gives (x^2+6x+8=0).\)

Step 2

Why this answer is correct

\(The correct answer is A. (x^2+6x+8=0). A monic equation is (x^2-(\)sum)x+product\(=0). Substituting sum (-6) gives (x^2+6x+8=0).\)

Step 3

Exam Tip

\(मोनिक समीकरण (x^2-(\)योग)x+गुणनफल=0) होता है। \(योग (-6) रखने पर (x^2+6x+8=0) मिलता है\)।
