निम्न में से (y) में द्विघात समीकरण कौन-सा है?
Which of the following is a quadratic equation in (y)?
Explanation opens after your attempt
Correct Answer
A. \(2y^2-3y+1=0\)
Concept
The highest power of (y) is (2), so it is quadratic in (y). The variable may be different, but the degree must be (2).
Why this answer is correct
The correct answer is A. \(2y^2-3y+1=0\). The highest power of (y) is (2), so it is quadratic in (y). The variable may be different, but the degree must be (2).
Exam Tip
चर (y) की सबसे बड़ी घात (2) है इसलिए यह (y) में द्विघात है। चर कोई भी हो सकता है पर घात (2) होनी चाहिए।
