What will be the roots of (18x^2-45x+14=0) by factorisation method?(18x^2-45x+14=0) को गुणनखंड विधि से हल करने पर मूल क्या होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x=\frac{1}{3},\frac{7}{3})(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.(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।
