यदि (f(x)=x-2+3x+2) और (g(x)=x+1) हैं, तो \(x \neq -1\) के लिए (\left\(\frac{f}{g}\right\)(2)) क्या होगा?

If (f(x)=x-2+3x+2) and (g(x)=x+1), what is (\left\(\frac{f}{g}\right\)(2)) for \(x \neq -1\)?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

(\frac{x-2+3x+2}{x+1}=\frac{(x+1)(x+2)}{x+1}=x+2), so at (x=2) the value is (4). Factorisation saves time.

Step 2

Why this answer is correct

The correct answer is A. (4). (\frac{x-2+3x+2}{x+1}=\frac{(x+1)(x+2)}{x+1}=x+2), so at (x=2) the value is (4). Factorisation saves time.

Step 3

Exam Tip

(\frac{x-2+3x+2}{x+1}=\frac{(x+1)(x+2)}{x+1}=x+2), इसलिए (x=2) पर मान (4) है। गुणनखंड बनाकर समय बचाएँ।
