समीकरण \(2x^2-9x+4=0\) के मूलों का योग और गुणनफल क्रमशः क्या हैं?
For \(2x^2-9x+4=0\), what are the sum and product of roots respectively?
Explanation opens after your attempt
A. \(\frac{9}{2}\) और (2)\(\frac{9}{2}\) and (2)
Concept
The sum is \(-\frac{b}{a}=\frac{9}{2}\) and the product is \(\frac{c}{a}=2\). Identify (a), (b), and (c) first.
Why this answer is correct
The correct answer is A. \(\frac{9}{2}\) और (2) / \(\frac{9}{2}\) and (2). The sum is \(-\frac{b}{a}=\frac{9}{2}\) and the product is \(\frac{c}{a}=2\). Identify (a), (b), and (c) first.
Exam Tip
योग \(-\frac{b}{a}=\frac{9}{2}\) और गुणनफल \(\frac{c}{a}=2\) है। पहले (a), (b), (c) पहचानें।
