erweitern sqrt(x^2+((4x)/(x-2))^2)

Lösung

erweitern

x^{2} + (\frac{4 x}{x - 2})^{2}

\frac{x ^{4} - 4 x ^{3} + 20 x ^{2}}{x ^{2} - 4 x + 4}

Schritte zur Lösung

x^{2} + (\frac{4 x}{x - 2})^{2}

(\frac{4 x}{x - 2})^{2} = \frac{4 ^{2} x ^{2}}{x ^{2} - 4 x + 4}

= x^{2} + \frac{4 ^{2} x ^{2}}{x ^{2} - 4 x + 4}

Füge

x^{2} + \frac{4 ^{2} x ^{2}}{x ^{2} - 4 x + 4}

zusammen:

\frac{x ^{4} - 4 x ^{3} + 20 x ^{2}}{x ^{2} - 4 x + 4}

= \frac{x ^{4} - 4 x ^{3} + 20 x ^{2}}{x ^{2} - 4 x + 4}

e x p an d \frac{3 x}{2} - \frac{3}{2 π} (100 - 3 x)

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

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