\(18x^2-45x+14=0\) को गुणनखंड विधि से हल करने पर मूल क्या होंगे?
What will be the roots of \(18x^2-45x+14=0\) by factorisation method?
Explanation opens after your attempt
A. \(x=\frac{1}{3},\frac{7}{3}\)
Concept
(18x-2-45x+14=(3x-1)(6x-14)), so the roots are \(\frac{1}{3}\) and \(\frac{7}{3}\). In exams, always check the final factors when a common factor appears.
Why this answer is correct
The correct answer is A. \(x=\frac{1}{3},\frac{7}{3}\). (18x-2-45x+14=(3x-1)(6x-14)), so the roots are \(\frac{1}{3}\) and \(\frac{7}{3}\). In exams, always check the final factors when a common factor appears.
Exam Tip
(18x-2-45x+14=(3x-1)(6x-14)), इसलिए मूल \(\frac{1}{3}\) और \(\frac{7}{3}\) हैं। परीक्षा में सामान्य गुणक हो तो अंतिम जाँच जरूर करें।
