erweitern-(5m(t+10s)^2)/(s^2)

Lösung

erweitern

- \frac{5 m ( t + 10 s ) ^{2}}{s ^{2}}

- \frac{5 m t ^{2}}{s ^{2}} - \frac{100 m t}{s} - 500 m

Schritte zur Lösung

- \frac{5 m ( t + 10 s ) ^{2}}{s ^{2}}

(t + 10 s)^{2} = t^{2} + 20 t s + 100 s^{2}

= - \frac{5 m ( t ^{2} + 20 t s + 100 s ^{2} )}{s ^{2}}

5 m (t^{2} + 20 t s + 100 s^{2}) : 5 m t^{2} + 100 m t s + 500 m s^{2}

= - \frac{5 m t ^{2} + 100 m t s + 500 m s ^{2}}{s ^{2}}

Wende Bruchregel an:

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

\frac{5 m t ^{2} + 100 m t s + 500 m s ^{2}}{s ^{2}} = - (\frac{5 m t ^{2}}{s ^{2}}) - (\frac{100 m t s}{s ^{2}}) - (\frac{500 m s ^{2}}{s ^{2}})

= - (\frac{5 m t ^{2}}{s ^{2}}) - (\frac{100 m t s}{s ^{2}}) - (\frac{500 m s ^{2}}{s ^{2}})
