यदि \(x^2-7x+10\) के शून्यक \(\alpha\) और \(\beta\) हैं, तो \(\alpha^2+\beta^2\) क्या है?

If \(\alpha\) and \(\beta\) are zeroes of \(x^2-7x+10\), what is \(\alpha^2+\beta^2\)?

Explanation opens after your attempt
Correct Answer

A. (29)

Step 1

Concept

(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Thus (72-2(10)=29).

Step 2

Why this answer is correct

The correct answer is A. (29). (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Thus (72-2(10)=29).

Step 3

Exam Tip

(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta) होता है। (72-2(10)=29) है।
