\(\frac{1}{x}+x=\frac{50}{7}\), \(x\neq0\), के हल क्या हैं?

What are the solutions of \(\frac{1}{x}+x=\frac{50}{7}\), \(x\neq0\)?

Explanation opens after your attempt
Correct Answer

A. \(x=7,\frac{1}{7}\)

Step 1

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.

Step 2

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.

Step 3

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।

For \(\frac{1}{x}+x=\frac{50}{7}\), \(x\neq0\), what quadratic form is obtained?

Explanation opens after your attempt
Correct Answer

A. \(7x^2-50x+7=0\)

Step 1

Concept

Multiplying both sides by (7x) gives \(7+7x^2=50x\), that is \(7x^2-50x+7=0\). In exams, remember the condition \(x\neq0\).

Step 2

Why this answer is correct

The correct answer is A. \(7x^2-50x+7=0\). Multiplying both sides by (7x) gives \(7+7x^2=50x\), that is \(7x^2-50x+7=0\). In exams, remember the condition \(x\neq0\).

Step 3

Exam Tip

दोनों पक्षों को (7x) से गुणा करने पर \(7+7x^2=50x\), यानी \(7x^2-50x+7=0\) मिलता है। परीक्षा में \(x\neq0\) शर्त याद रखें।
