किस विकल्प में दिया गया समीकरण द्विघात नहीं रहेगा?
In which option will the given equation not remain quadratic?
Explanation opens after your attempt
Correct Answer
A. ((t-2)x-2+5x+1=0), (t=2)
Concept
In the first option, putting (t=2) makes the coefficient of \(x^2\) equal to (0). Then the equation becomes linear.
Why this answer is correct
The correct answer is A. ((t-2)x-2+5x+1=0), (t=2). In the first option, putting (t=2) makes the coefficient of \(x^2\) equal to (0). Then the equation becomes linear.
Exam Tip
पहले विकल्प में (t=2) रखने पर \(x^2\) का गुणांक (0) हो जाता है। तब समीकरण रैखिक बन जाता है।
