erweitern ((2c-10)^2)/(112)+50

Lösung

erweitern

\frac{( 2 c - 10 ) ^{2}}{112} + 50

\frac{c ^{2}}{28} - \frac{5 c}{14} + \frac{25}{28} + 50

Schritte zur Lösung

\frac{( 2 c - 10 ) ^{2}}{112} + 50

\frac{( 2 c - 10 ) ^{2}}{112} = \frac{c ^{2} - 10 c + 25}{28}

= \frac{c ^{2} - 10 c + 25}{28} + 50

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{c ^{2} - 10 c + 25}{28} = \frac{c ^{2}}{28} - \frac{10 c}{28} + \frac{25}{28}

= \frac{c ^{2}}{28} - \frac{10 c}{28} + \frac{25}{28} + 50
