\(\frac{1}{x}+x=\frac{50}{7}\), \(x\neq0\), के हल क्या हैं?
What are the solutions of \(\frac{1}{x}+x=\frac{50}{7}\), \(x\neq0\)?
Explanation opens after your attempt
A. \(x=7,\frac{1}{7}\)
Concept
(7x-2-50x+7=(7x-1)(x-7)), so \(x=\frac{1}{7}\) and (7). In exams, check whether obtained roots are valid in the original equation.
Why this answer is correct
The correct answer is A. \(x=7,\frac{1}{7}\). (7x-2-50x+7=(7x-1)(x-7)), so \(x=\frac{1}{7}\) and (7). In exams, check whether obtained roots are valid in the original equation.
Exam Tip
(7x-2-50x+7=(7x-1)(x-7)), इसलिए \(x=\frac{1}{7}\) और (7) हैं। परीक्षा में प्राप्त हल मूल समीकरण में मान्य हैं या नहीं जांचें।
