समीकरण ((m-2)x-2+3x+1=0) द्विघात कब होगा?
When will ((m-2)x-2+3x+1=0) be quadratic?
Explanation opens after your attempt
Correct Answer
B. \(m\neq 2\)
Concept
For the equation to be quadratic, the coefficient of \(x^2\) must not be (0). Thus \(m-2\neq 0\), so \(m\neq 2\).
Why this answer is correct
The correct answer is B. \(m\neq 2\). For the equation to be quadratic, the coefficient of \(x^2\) must not be (0). Thus \(m-2\neq 0\), so \(m\neq 2\).
Exam Tip
द्विघात होने के लिए \(x^2\) का गुणांक (0) नहीं होना चाहिए। इसलिए \(m-2\neq 0\) यानी \(m\neq 2\)।
