erweitern ((-1))/((4(2x+1)))-1/4 (2x-1)

Lösung

erweitern

\frac{( - 1 )}{( 4 ( 2 x + 1 ) )} - \frac{1}{4} (2 x - 1)

- \frac{1}{4 ( 2 x + 1 )} - \frac{x}{2} + \frac{1}{4}

Schritte zur Lösung

\frac{- 1}{4 ( 2 x + 1 )} - \frac{1}{4} (2 x - 1)

Schreibe

- \frac{1}{4} (2 x - 1)

um:

- \frac{x}{2} + \frac{1}{4}

= \frac{- 1}{4 ( 2 x + 1 )} - \frac{x}{2} + \frac{1}{4}

Wende Bruchregel an:

\frac{- a}{b} = - \frac{a}{b}

\frac{- 1}{4 ( 2 x + 1 )} = - \frac{1}{4 ( 2 x + 1 )}

= - \frac{1}{4 ( 2 x + 1 )} - \frac{x}{2} + \frac{1}{4}
