\(3x^2+5x-2=0\) को गुणनखंड विधि से हल करने पर मूल क्या होंगे?
What roots are obtained by solving \(3x^2+5x-2=0\) by factorisation?
Explanation opens after your attempt
A. \(x=\frac{1}{3},-2\)
Concept
(3x-2+5x-2=(3x-1)(x+2)), so the roots are \(\frac{1}{3}\) and (-2). In exams, solve (3x-1=0) carefully.
Why this answer is correct
The correct answer is A. \(x=\frac{1}{3},-2\). (3x-2+5x-2=(3x-1)(x+2)), so the roots are \(\frac{1}{3}\) and (-2). In exams, solve (3x-1=0) carefully.
Exam Tip
(3x-2+5x-2=(3x-1)(x+2)), इसलिए मूल \(\frac{1}{3}\) और (-2) हैं। परीक्षा में (3x-1=0) को सावधानी से हल करें।
