If (f(x)=\frac{1}{x-1}) and (g(x)=\frac{1}{x+1}), what is ((f+g)(x))?यदि (f(x)=\frac{1}{x-1}) और (g(x)=\frac{1}{x+1}) हैं, तो ((f+g)(x)) क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{2x}{x^2-1} )( \frac{2x}{x^2-1} )
(\frac{1}{x-1}+\frac{1}{x+1}=\frac{(x+1)+(x-1)}{x^2-1}=\frac{2x}{x^2-1}). Add the numerators correctly after taking the common denominator.(\frac{1}{x-1}+\frac{1}{x+1}=\frac{(x+1)+(x-1)}{x^2-1}=\frac{2x}{x^2-1})। जोड़ में अंशों को सही तरह जोड़ें।
