यदि \(3x^2+2x-1\) के शून्यक \(\alpha\) और \(\beta\) हैं, तो (\(\alpha+\beta\)2) का मान क्या है?

If \(\alpha\) and \(\beta\) are zeroes of \(3x^2+2x-1\), what is (\(\alpha+\beta\)2)?

Explanation opens after your attempt
Correct Answer

A. \(\frac{4}{9}\)

Step 1

Concept

\(\alpha+\beta=-\frac{2}{3}\). Therefore, (\(\alpha+\beta\)2=\frac{4}{9}).

Step 2

Why this answer is correct

The correct answer is A. \(\frac{4}{9}\). \(\alpha+\beta=-\frac{2}{3}\). Therefore, (\(\alpha+\beta\)2=\frac{4}{9}).

Step 3

Exam Tip

\(\alpha+\beta=-\frac{2}{3}\) है। इसलिए (\(\alpha+\beta\)2=\frac{4}{9}) होगा।
