समीकरण \(5x^2-18x+9=0\) के मूलों का योग और गुणनफल क्रमशः क्या हैं?

For \(5x^2-18x+9=0\), what are the sum and product of roots respectively?

Explanation opens after your attempt
Correct Answer

A. \(\frac{18}{5}\) और \(\frac{9}{5}\)\(\frac{18}{5}\) and \(\frac{9}{5}\)

Step 1

Concept

The sum is \(-\frac{b}{a}=\frac{18}{5}\) and the product is \(\frac{c}{a}=\frac{9}{5}\). Identify (a), (b), and (c) first.

Step 2

Why this answer is correct

The correct answer is A. \(\frac{18}{5}\) और \(\frac{9}{5}\) / \(\frac{18}{5}\) and \(\frac{9}{5}\). The sum is \(-\frac{b}{a}=\frac{18}{5}\) and the product is \(\frac{c}{a}=\frac{9}{5}\). Identify (a), (b), and (c) first.

Step 3

Exam Tip

योग \(-\frac{b}{a}=\frac{18}{5}\) और गुणनफल \(\frac{c}{a}=\frac{9}{5}\) है। पहले (a), (b), (c) पहचानें।
