\(x^2+7x+10=0\) के मूल क्या हैं?

What are the roots of \(x^2+7x+10=0\)?

Explanation opens after your attempt
Correct Answer

A. (x=-5,-2)

Step 1

Concept

((x+5)(x+2)=0), so (x=-5) and (x=-2). In exams, from ((x+a)=0), write (x=-a).

Step 2

Why this answer is correct

The correct answer is A. (x=-5,-2). ((x+5)(x+2)=0), so (x=-5) and (x=-2). In exams, from ((x+a)=0), write (x=-a).

Step 3

Exam Tip

((x+5)(x+2)=0), इसलिए (x=-5) और (x=-2) हैं। परीक्षा में ((x+a)=0) से (x=-a) लिखें।
