(\frac{- 56}{7} bi g)^{2} (7 - 56) 2

2 \cdot 7 (i \frac{- 56}{7} b g)^{2} - 2 \cdot 56 (i \frac{- 56}{7} b g)^{2}

Schritte zur Lösung

(\frac{- 56}{7} bi g)^{2} (7 - 56) \cdot 2

= 2 (7 - 56) (i \frac{- 56}{7} b g)^{2}

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = (\frac{- 56}{7} bi g)^{2} \cdot 2, b = 7, c = 56

= (\frac{- 56}{7} bi g)^{2} \cdot 2 \cdot 7 - (\frac{- 56}{7} bi g)^{2} \cdot 2 \cdot 56

= 2 \cdot 7 (i \frac{- 56}{7} b g)^{2} - 2 \cdot 56 (i \frac{- 56}{7} b g)^{2}
