समीकरण \(x^2-3x+s=0\) के समान वास्तविक मूलों के लिए (s) का मान क्या होगा?

What is the value of (s) for equal real roots of \(x^2-3x+s=0\)?

Explanation opens after your attempt
Correct Answer

A. \(\frac{9}{4}\)

Step 1

Concept

For equal roots (D=0), so ((-3)2-4s=0) gives \(s=\frac{9}{4}\). Do not fear fractional answers.

Step 2

Why this answer is correct

The correct answer is A. \(\frac{9}{4}\). For equal roots (D=0), so ((-3)2-4s=0) gives \(s=\frac{9}{4}\). Do not fear fractional answers.

Step 3

Exam Tip

समान मूलों के लिए (D=0), इसलिए ((-3)2-4s=0) से \(s=\frac{9}{4}\)। भिन्न उत्तर से न डरें।
