\(5x^2+16x+3=0\) को हल करने पर मूल क्या होंगे?
What will be the roots after solving \(5x^2+16x+3=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=-3,-\frac{1}{5}\)
Concept
(5x-2+16x+3=(5x+1)(x+3)), so the roots are \(-\frac{1}{5}\) and (-3). In exams, positive factors give negative roots.
Why this answer is correct
The correct answer is A. \(x=-3,-\frac{1}{5}\). (5x-2+16x+3=(5x+1)(x+3)), so the roots are \(-\frac{1}{5}\) and (-3). In exams, positive factors give negative roots.
Exam Tip
(5x-2+16x+3=(5x+1)(x+3)), इसलिए मूल \(-\frac{1}{5}\) और (-3) हैं। परीक्षा में धनात्मक गुणनखंडों से ऋणात्मक मूल मिलते हैं।
