यदि (4) समीकरण \(x^2+kx-32=0\) का मूल है तो (k) का मान क्या होगा?
If (4) is a root of \(x^2+kx-32=0\), what is the value of (k)?
Explanation opens after your attempt
A. (4)
Concept
Putting (x=4) gives (16+4k-32=0), so (k=4). Substitute the given root directly for a parameter.
Why this answer is correct
The correct answer is A. (4). Putting (x=4) gives (16+4k-32=0), so (k=4). Substitute the given root directly for a parameter.
Exam Tip
(x=4) रखने पर (16+4k-32=0) इसलिए (k=4) है। पैरामीटर के लिए दिए गए मूल को सीधे रखें।
