यदि \(\alpha\) और \(\beta\) समीकरण \(x^2+3x-18=0\) के मूल हैं तो \(\left|\alpha-\beta\right|\) का मान क्या है?
If \(\alpha\) and \(\beta\) are roots of \(x^2+3x-18=0\), what is the value of \(\left|\alpha-\beta\right|\)?
Explanation opens after your attempt
A. (9)
Concept
The roots are (3) and (-6). Therefore (\left|\alpha-\beta\right|=\left|3-(-6)\right|=9).
Why this answer is correct
The correct answer is A. (9). The roots are (3) and (-6). Therefore (\left|\alpha-\beta\right|=\left|3-(-6)\right|=9).
Exam Tip
समीकरण के मूल (3) और (-6) हैं। इसलिए (\left|\alpha-\beta\right|=\left|3-(-6)\right|=9) है।
