\(2x^2+7x+6=0\) को हल करने पर मूल क्या होंगे?
What will be the roots after solving \(2x^2+7x+6=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=-\frac{3}{2},-2\)
Concept
(2x-2+7x+6=(2x+3)(x+2)), so \(x=-\frac{3}{2}\) and (-2). In exams, positive factors give negative roots.
Why this answer is correct
The correct answer is A. \(x=-\frac{3}{2},-2\). (2x-2+7x+6=(2x+3)(x+2)), so \(x=-\frac{3}{2}\) and (-2). In exams, positive factors give negative roots.
Exam Tip
(2x-2+7x+6=(2x+3)(x+2)), इसलिए \(x=-\frac{3}{2}\) और (-2) हैं। परीक्षा में धनात्मक गुणनखंडों से ऋणात्मक मूल मिलते हैं।
