erweitern ((x-6)-x^2(x-2)^2)/((x-2)^2)

Lösung

erweitern

\frac{( x - 6 ) - x ^{2} ( x - 2 ) ^{2}}{( x - 2 ) ^{2}}

\frac{x - 6 - x ^{4} + 4 x ^{3} - 4 x ^{2}}{x ^{2} - 4 x + 4}

Schritte zur Lösung

\frac{( x - 6 ) - x ^{2} ( x - 2 ) ^{2}}{( x - 2 ) ^{2}}

Entferne die Klammern:

(a) = a

= \frac{x - 6 - x ^{2} ( x - 2 ) ^{2}}{( x - 2 ) ^{2}}

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

= \frac{x - 6 - x ^{2} ( x - 2 ) ^{2}}{x ^{2} - 4 x + 4}

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

= \frac{x - 6 - x ^{2} ( x ^{2} - 4 x + 4 )}{x ^{2} - 4 x + 4}
