यदि (f(x)=x-2+6x+9) और (g(x)=x+3) हैं, तो \(x \neq -3\) के लिए (\left\(\frac{f}{g}\right\)(0)) क्या है?
If (f(x)=x-2+6x+9) and (g(x)=x+3), what is (\left\(\frac{f}{g}\right\)(0)) for \(x \neq -3\)?
Explanation opens after your attempt
A. (3)
Concept
(\frac{x-2+6x+9}{x+3}=\frac{(x+3)2}{x+3}=x+3), hence the value at (x=0) is (3). The perfect square identity is useful.
Why this answer is correct
The correct answer is A. (3). (\frac{x-2+6x+9}{x+3}=\frac{(x+3)2}{x+3}=x+3), hence the value at (x=0) is (3). The perfect square identity is useful.
Exam Tip
(\frac{x-2+6x+9}{x+3}=\frac{(x+3)2}{x+3}=x+3), अतः (x=0) पर मान (3) है। पूर्ण वर्ग पहचान उपयोगी है।
