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

Lösung

erweitern

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

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

Schritte zur Lösung

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

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

= \frac{2 x y + x ^{2} - 2 x + y ^{2} - 2 y + 1}{x + y}

e x p an d (t^{3} e^{t} + 2 e)^{2}

e x p an d \frac{( n + 1 ) ( 6 n ^{4} + 9 n ^{3} + n ^{2} - n )}{30}

e x p an d \frac{x + 1 + 2 x ^{3} + 3 x ^{2}}{x ^{2} ( x + 1 )}

e x p an d \frac{1}{1 - \frac{v ^{2}}{c ^{2}}}

e x p an d \frac{1}{x ( 1 + t x )}
