\(3x^2+11x+10=0\) को हल करने पर मूल क्या होंगे?
What will be the roots after solving \(3x^2+11x+10=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=-2,-\frac{5}{3}\)
Concept
(3x-2+11x+10=(3x+5)(x+2)), so the roots are \(-\frac{5}{3}\) and (-2). In exams, positive factors give negative roots.
Why this answer is correct
The correct answer is A. \(x=-2,-\frac{5}{3}\). (3x-2+11x+10=(3x+5)(x+2)), so the roots are \(-\frac{5}{3}\) and (-2). In exams, positive factors give negative roots.
Exam Tip
(3x-2+11x+10=(3x+5)(x+2)), इसलिए मूल \(-\frac{5}{3}\) और (-2) हैं। परीक्षा में धनात्मक गुणनखंडों से ऋणात्मक मूल मिलते हैं।
