What is the sum of squares of the roots of \(x^2-6x+5=0\)?
Explanation opens after your attempt
A. (26)
Concept
Here \(\alpha+\beta=6\) and \(\alpha\beta=5\). Thus \(\alpha^2+\beta^2=36-10=26\).
Why this answer is correct
The correct answer is A. (26). Here \(\alpha+\beta=6\) and \(\alpha\beta=5\). Thus \(\alpha^2+\beta^2=36-10=26\).
Exam Tip
यहां \(\alpha+\beta=6\) और \(\alpha\beta=5\) है। \(\alpha^2+\beta^2=36-10=26\) होगा।
