समीकरण \(\frac{1}{x^2}+x+1=0\) द्विघात समीकरण क्यों नहीं है?
Why is \(\frac{1}{x^2}+x+1=0\) not a quadratic equation?
Explanation opens after your attempt
Correct Answer
A. क्योंकि इसमें (x) की ऋणात्मक घात हैBecause it has a negative power of (x)
Concept
\(\frac{1}{x^2}=x^{-2}\), which is not polynomial form. A quadratic equation cannot have a negative power of the variable.
Why this answer is correct
The correct answer is A. क्योंकि इसमें (x) की ऋणात्मक घात है / Because it has a negative power of (x). \(\frac{1}{x^2}=x^{-2}\), which is not polynomial form. A quadratic equation cannot have a negative power of the variable.
Exam Tip
\(\frac{1}{x^2}=x^{-2}\) है जो बहुपद रूप नहीं है। द्विघात समीकरण में चर की ऋणात्मक घात नहीं होती।
