Author: Muft Shiksha Editorial Team Published:
Explanation opens after your attempt
Correct Answer

C. ((x+3)(x+7))

Step 1

Concept

The expression simplifies to \(x^2+4x+3\), so the factors are ((x+1)(x+3)). First simplify the given terms carefully.

Step 2

Why this answer is correct

The correct answer is C. ((x+3)(x+7)). The expression simplifies to \(x^2+4x+3\), so the factors are ((x+1)(x+3)). First simplify the given terms carefully.

Step 3

Exam Tip

व्यंजक \(x^2+4x+3\) नहीं बल्कि \(x^2+4x+3\) है, इसलिए गुणनखंड ((x+1)(x+3)) होंगे। ध्यान दें कि दिए पदों को पहले सरल करें।
