expand (x+h+1)/((x+h)^2+1)

expand

\frac{x + h + 1}{( x + h ) ^{2} + 1}

\frac{x + h + 1}{x ^{2} + 2 x h + h ^{2} + 1}

Solution steps

\frac{x + h + 1}{( x + h ) ^{2} + 1}

Expand

(x + h)^{2} + 1 : x^{2} + 2 x h + h^{2} + 1

= \frac{x + h + 1}{x ^{2} + 2 x h + h ^{2} + 1}

\frac{x ^{2} ( x + h ) - x ^{2}}{h}

\frac{- 3 x + 3}{( x - 3 ) ( x - 5 )}
