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
A. (x+2)
Concept
(x-2+4x+4=(x+2)2), so the quotient is (x+2) and (x=-2) is excluded. The square identity is useful.
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.
Exam Tip
(x-2+4x+4=(x+2)2), इसलिए भागफल (x+2) है और (x=-2) हटेगा। वर्ग पहचान उपयोगी है।
