\(x^2-9+4x+12\) को गुणनखंडित करने पर क्या मिलेगा?
What is obtained by factorising \(x^2-9+4x+12\)?
Explanation opens after your attempt
C. ((x+3)(x+7))
Concept
The expression simplifies to \(x^2+4x+3\), so the factors are ((x+1)(x+3)). First simplify the given terms carefully.
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.
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।
