erweitern (s+1/(sqrt(2)))^2

Lösung

erweitern

(s + \frac{1}{2})^{2}

\frac{2 s ^{2} + 2 2 s + 1}{2}

Schritte zur Lösung

(s + \frac{1}{2})^{2}

Wende Formel für perfekte quadratische Gleichungen an:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(s + \frac{1}{2})^{2} = s^{2} + 2 s \frac{1}{2} + (\frac{1}{2})^{2}

= s^{2} + 2 s \frac{1}{2} + (\frac{1}{2})^{2}

Vereinfache

s^{2} + 2 s \frac{1}{2} + (\frac{1}{2})^{2} : \frac{2 s ^{2} + 2 2 s + 1}{2}

= \frac{2 s ^{2} + 2 2 s + 1}{2}
