समीकरण \(4x^2+8x+3=0\) में मूलों के वर्गों का योग क्या है?
What is the sum of squares of the roots of \(4x^2+8x+3=0\)?
Explanation opens after your attempt
Correct Answer
A. \( \frac{5}{2} \)
Concept
(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here ((-2)2-2\cdot\frac{3}{4}=\frac{5}{2}).
Why this answer is correct
The correct answer is A. \( \frac{5}{2} \). (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here ((-2)2-2\cdot\frac{3}{4}=\frac{5}{2}).
Exam Tip
(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta) होता है। यहाँ ((-2)2-2\cdot\frac{3}{4}=\frac{5}{2})।
