Schritte zur Lösung

(e^{2} - \frac{1}{e}) \cdot 9

= 9 (e^{2} - \frac{1}{e})

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = 9, b = e^{2}, c = \frac{1}{e}

= 9 e^{2} - 9 \cdot \frac{1}{e}

9 \cdot \frac{1}{e} = \frac{9}{e}

= 9 e^{2} - \frac{9}{e}

e x p an d - \frac{x ^{2}}{3 ( x - 1 ) ( x + 1 ) ( x ^{2} - 2 )}

e x p an d \frac{7 ( m + 2 )}{3 ( m - 2 ) ( m + 4 )}

e x p an d (2 x - 1) (x - 1 + 5) (x - 1 - 5)

e x p an d x^{\frac{1}{2}} (x^{- \frac{3}{2}} + x^{- \frac{1}{2}})

e x p an d (5 x + \frac{π}{180})^{2}
