erweitern (x^2+2x+3)/((x-1)(x+1)^2)

Lösung

erweitern

\frac{x ^{2} + 2 x + 3}{( x - 1 ) ( x + 1 ) ^{2}}

\frac{x ^{2} + 2 x + 3}{x ^{3} + x ^{2} - x - 1}

Schritte zur Lösung

\frac{x ^{2} + 2 x + 3}{( x - 1 ) ( x + 1 ) ^{2}}

(x + 1)^{2} = x^{2} + 2 x + 1

= \frac{x ^{2} + 2 x + 3}{( x - 1 ) ( x ^{2} + 2 x + 1 )}
