यदि (f(x)=x-2+4x+4) और (g(x)=x+2) हों, तो \(x\ne -2\) के लिए (\left\(\frac{f}{g}\right\)(x)) क्या है?

If (f(x)=x-2+4x+4) and (g(x)=x+2), what is (\left\(\frac{f}{g}\right\)(x)) for \(x\ne -2\)?

Explanation opens after your attempt
Correct Answer

A. (x+2)

Step 1

Concept

(x-2+4x+4=(x+2)2), so the quotient is (x+2) and (x=-2) is excluded. The square identity is useful.

Step 2

Why this answer is correct

The correct answer is A. (x+2). (x-2+4x+4=(x+2)2), so the quotient is (x+2) and (x=-2) is excluded. The square identity is useful.

Step 3

Exam Tip

(x-2+4x+4=(x+2)2), इसलिए भागफल (x+2) है और (x=-2) हटेगा। वर्ग पहचान उपयोगी है।
