यदि (f(x)=x-2-9) और (g(x)=x-3) हों, तो \(x \ne 3\) के लिए (\left\(\frac{f}{g}\right\)(x)) क्या होगा?
If (f(x)=x-2-9) and (g(x)=x-3), what is (\left\(\frac{f}{g}\right\)(x)) for \(x \ne 3\)?
Explanation opens after your attempt
A. (x+3)
Concept
(\frac{x-2-9}{x-3}=\frac{(x-3)(x+3)}{x-3}=x+3), but (x=3) is excluded. In division, the denominator must not be zero.
Why this answer is correct
The correct answer is A. (x+3). (\frac{x-2-9}{x-3}=\frac{(x-3)(x+3)}{x-3}=x+3), but (x=3) is excluded. In division, the denominator must not be zero.
Exam Tip
(\frac{x-2-9}{x-3}=\frac{(x-3)(x+3)}{x-3}=x+3), लेकिन (x=3) हटेगा। भाग में हर शून्य न हो।
