erweitern (((2x-1)^3(26-6x)))/((4-x)^3)

Lösung

erweitern

\frac{( ( 2 x - 1 ) ^{3} ( 26 - 6 x ) )}{( 4 - x ) ^{3}}

\frac{- 48 x ^{4} + 280 x ^{3} - 348 x ^{2} + 162 x - 26}{64 - 48 x + 12 x ^{2} - x ^{3}}

Schritte zur Lösung

\frac{( 2 x - 1 ) ^{3} ( 26 - 6 x )}{( 4 - x ) ^{3}}

(4 - x)^{3} = 64 - 48 x + 12 x^{2} - x^{3}

= \frac{( 2 x - 1 ) ^{3} ( - 6 x + 26 )}{64 - 48 x + 12 x ^{2} - x ^{3}}

(2 x - 1)^{3} = 8 x^{3} - 12 x^{2} + 6 x - 1

= \frac{( 8 x ^{3} - 12 x ^{2} + 6 x - 1 ) ( - 6 x + 26 )}{64 - 48 x + 12 x ^{2} - x ^{3}}
