Correct Answer

A. (x+1), \(x\ne 1\)

Explanation

Simple Explanation

(f(x)=\frac{x-2-1}{x-1}=x+1), पर (g(x)\ne 0) के लिए \(x\ne 1\)। अज्ञात गुणक निकालते समय विभाजन का प्रतिबंध देखें। / (f(x)=\frac{x-2-1}{x-1}=x+1), but \(x\ne 1\) because (g(x)\ne 0). While finding an unknown factor check the division restriction.
