\(5x^2-13x-6=0\) के मूल क्या हैं?

What are the roots of \(5x^2-13x-6=0\)?

Explanation opens after your attempt
Correct Answer

A. \(x=3,-\frac{2}{5}\)

Step 1

Concept

(5x-2-13x-6=(5x+2)(x-3)), so the roots are (3) and \(-\frac{2}{5}\). In exams, reverse the signs from linear factors to write roots.

Step 2

Why this answer is correct

The correct answer is A. \(x=3,-\frac{2}{5}\). (5x-2-13x-6=(5x+2)(x-3)), so the roots are (3) and \(-\frac{2}{5}\). In exams, reverse the signs from linear factors to write roots.

Step 3

Exam Tip

(5x-2-13x-6=(5x+2)(x-3)), इसलिए मूल (3) और \(-\frac{2}{5}\) हैं। परीक्षा में रैखिक गुणनखंडों के चिन्ह उलटकर मूल लिखें।
