ग्राफ \(y=x^2\) और (y=2x+3) के प्रतिच्छेद बिंदुओं की संख्या कितनी है?
How many intersection points do the graphs \(y=x^2\) and (y=2x+3) have?
Explanation opens after your attempt
A. (2)
Concept
Solving \(x^2=2x+3\) gives \(x^2-2x-3=0\), which has two real roots. Intersections equal the number of real solutions.
Why this answer is correct
The correct answer is A. (2). Solving \(x^2=2x+3\) gives \(x^2-2x-3=0\), which has two real roots. Intersections equal the number of real solutions.
Exam Tip
\(x^2=2x+3\) से \(x^2-2x-3=0\), जिसके दो वास्तविक मूल हैं। प्रतिच्छेदों की संख्या समीकरण के वास्तविक हलों से मिलती है।
