vereinfachen (sqrt(r)-sqrt(t))^2

Lösung

vereinfachen

(r - t)^{2}

r - 2 r t + t

Schritte zur Lösung

(r - t)^{2}

Wende Formel für perfekte quadratische Gleichungen an:

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

(r - t)^{2} = (r)^{2} - 2 r t + (t)^{2}

= (r)^{2} - 2 r t + (t)^{2}

(r)^{2} = r

(t)^{2} = t

= r - 2 r t + t
