\(\frac{1}{x}+x=\frac{5}{2}\), \(x\neq0\), के हल क्या हैं?
What are the solutions of \(\frac{1}{x}+x=\frac{5}{2}\), \(x\neq0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=2,\frac{1}{2}\)
Concept
(2x-2-5x+2=(2x-1)(x-2)), so \(x=\frac{1}{2}\) and (2). In exams, check whether obtained roots are valid in the original equation.
Why this answer is correct
The correct answer is A. \(x=2,\frac{1}{2}\). (2x-2-5x+2=(2x-1)(x-2)), so \(x=\frac{1}{2}\) and (2). In exams, check whether obtained roots are valid in the original equation.
Exam Tip
(2x-2-5x+2=(2x-1)(x-2)), इसलिए \(x=\frac{1}{2}\) और (2) हैं। परीक्षा में प्राप्त हल मूल समीकरण में मान्य हैं या नहीं जांचें।
