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
Correct Answer

A. (9)

Step 1

Concept

The roots are (3) and (-6). Therefore (\left|\alpha-\beta\right|=\left|3-(-6)\right|=9).

Step 2

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).

Step 3

Exam Tip

समीकरण के मूल (3) और (-6) हैं। इसलिए (\left|\alpha-\beta\right|=\left|3-(-6)\right|=9) है।
