यदि \(x^2+10x+c=0\) पूर्ण वर्ग द्विघात समीकरण है, तो (c) का मान क्या होगा?
If \(x^2+10x+c=0\) is a perfect square quadratic equation, what is the value of (c)?
Explanation opens after your attempt
A. (25)
Concept
For a perfect square, (x-2+10x+c=(x+5)2) is needed. Hence (c=25).
Why this answer is correct
The correct answer is A. (25). For a perfect square, (x-2+10x+c=(x+5)2) is needed. Hence (c=25).
Exam Tip
पूर्ण वर्ग के लिए (x-2+10x+c=(x+5)2) होना चाहिए। इसलिए (c=25) होगा।
