What is the sum of squares of the roots of \(x^2-9x+14=0\)?

Explanation opens after your attempt
Correct Answer

A. (53)

Step 1

Concept

Here \(\alpha+\beta=9\) and \(\alpha\beta=14\). Thus \(\alpha^2+\beta^2=81-28=53\).

Step 2

Why this answer is correct

The correct answer is A. (53). Here \(\alpha+\beta=9\) and \(\alpha\beta=14\). Thus \(\alpha^2+\beta^2=81-28=53\).

Step 3

Exam Tip

यहां \(\alpha+\beta=9\) और \(\alpha\beta=14\) है। \(\alpha^2+\beta^2=81-28=53\) होगा।
