यदि (f(x)=\frac{x-2+1}{x}) और (g(x)=\frac{x-2-1}{x}) हैं, तो ((f-g)(x)) क्या है?
If (f(x)=\frac{x-2+1}{x}) and (g(x)=\frac{x-2-1}{x}), what is ((f-g)(x))?
Explanation opens after your attempt
Correct Answer
A. \(\frac{2}{x}\), \(x\ne 0\)
Concept
With a common denominator, (f-g=\frac{x-2+1-\(x^2-1\)}{x}=\frac{2}{x}), where \(x\ne 0\). In subtraction, both signs of the second numerator change.
Why this answer is correct
The correct answer is A. \(\frac{2}{x}\), \(x\ne 0\). With a common denominator, (f-g=\frac{x-2+1-\(x^2-1\)}{x}=\frac{2}{x}), where \(x\ne 0\). In subtraction, both signs of the second numerator change.
Exam Tip
समान हर से (f-g=\frac{x-2+1-\(x^2-1\)}{x}=\frac{2}{x}), जहां \(x\ne 0\)। घटाव में दूसरे अंश के दोनों चिन्ह बदलते हैं।
