यदि \(x^2+2x-8=0\) के मूल \(\alpha,\beta\) हैं, तो (\(\alpha+\beta\)2) का मान क्या है?
If \(\alpha,\beta\) are roots of \(x^2+2x-8=0\), what is (\(\alpha+\beta\)2)?
Explanation opens after your attempt
A. (4)
Concept
The sum of roots is (-2). Therefore (\(\alpha+\beta\)2=(-2)2=4).
Why this answer is correct
The correct answer is A. (4). The sum of roots is (-2). Therefore (\(\alpha+\beta\)2=(-2)2=4).
