समीकरण \(0x^2+2x+3=0\) द्विघात क्यों नहीं है?
Why is \(0x^2+2x+3=0\) not quadratic?
Explanation opens after your attempt
Correct Answer
B. क्योंकि \(x^2\) का गुणांक (0) हैBecause the coefficient of \(x^2\) is (0)
Concept
Here the coefficient of \(x^2\) is (0), so the \(x^2\) term disappears. For a quadratic equation, \(a\neq 0\) is necessary.
Why this answer is correct
The correct answer is B. क्योंकि \(x^2\) का गुणांक (0) है / Because the coefficient of \(x^2\) is (0). Here the coefficient of \(x^2\) is (0), so the \(x^2\) term disappears. For a quadratic equation, \(a\neq 0\) is necessary.
Exam Tip
यहाँ \(x^2\) का गुणांक (0) है इसलिए \(x^2\) पद समाप्त हो जाता है। द्विघात के लिए \(a\neq 0\) जरूरी है।
