\(x^2+4x-12=0\) के मूल क्या हैं?

What are the roots of \(x^2+4x-12=0\)?

Explanation opens after your attempt
Correct Answer

A. (x=2,-6)

Step 1

Concept

Since ((x+2)2=16), \(x+2=\pm4\), so (x=2,-6). In exams, use \(\pm\) to get both answers.

Step 2

Why this answer is correct

The correct answer is A. (x=2,-6). Since ((x+2)2=16), \(x+2=\pm4\), so (x=2,-6). In exams, use \(\pm\) to get both answers.

Step 3

Exam Tip

((x+2)2=16), इसलिए \(x+2=\pm4\) और (x=2,-6) हैं। परीक्षा में \(\pm\) से दोनों उत्तर निकालें।
