कौन-सा विकल्प द्विघात समीकरण नहीं है?
Which option is not a quadratic equation?
Explanation opens after your attempt
Correct Answer
C. \(x+\frac{1}{x}=2\)
Concept
In \(x+\frac{1}{x}=2\), the variable is in the denominator, so it is not directly in standard quadratic form. A quadratic polynomial form has no negative power.
Why this answer is correct
The correct answer is C. \(x+\frac{1}{x}=2\). In \(x+\frac{1}{x}=2\), the variable is in the denominator, so it is not directly in standard quadratic form. A quadratic polynomial form has no negative power.
Exam Tip
\(x+\frac{1}{x}=2\) में चर हर में है, इसलिए यह सीधे द्विघात मानक रूप में नहीं है। द्विघात बहुपद रूप में ऋणात्मक घात नहीं होती।
