Quadratic Equations Introduction to Quadratic Equations Class 10 Level 30
यदि \(x^2-19x+84=0\) के मूल \(\alpha,\beta\) हैं, तो (\(\alpha+\beta\)2) का मान क्या है?
If \(\alpha,\beta\) are roots of \(x^2-19x+84=0\), what is (\(\alpha+\beta\)2)?
Explanation opens after your attempt
Step 1
Concept
The sum of roots is (19). Therefore (\(\alpha+\beta\)2=192=361).
Step 2
Why this answer is correct
The correct answer is A. (361). The sum of roots is (19). Therefore (\(\alpha+\beta\)2=192=361).
Step 3
Exam Tip
मूलों का योग (19) है। इसलिए (\(\alpha+\beta\)2=192=361)।
