व्यंजक (\(t^2-4\)x-2+5x+3) रेखीय बहुपद कब बनेगा?
When will (\(t^2-4\)x-2+5x+3) become a linear polynomial?
Explanation opens after your attempt
A. जब (t=2) या (t=-2)When (t=2) or (t=-2)
Concept
To become linear, the coefficient of \(x^2\) must be (0). From \(t^2-4=0\), we get \(t=\pm2\).
Why this answer is correct
The correct answer is A. जब (t=2) या (t=-2) / When (t=2) or (t=-2). To become linear, the coefficient of \(x^2\) must be (0). From \(t^2-4=0\), we get \(t=\pm2\).
Exam Tip
रेखीय बनने के लिए \(x^2\) का गुणांक (0) होना चाहिए। \(t^2-4=0\) से \(t=\pm2\) मिलता है।
