s q r (4 + (2 tan^{2} (x)))

4 s q r + 2 s q r tan^{2} (x)

Schritte zur Lösung

s q r (4 + (2 tan^{2} (x)))

Vereinfache

4 + (2 tan^{2} (x)) : 4 + 2 tan^{2} (x)

= s q r (4 + 2 tan^{2} (x))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

s q r (4 + 2 tan^{2} (x)) = s q r \cdot 4 + s q r \cdot 2 tan^{2} (x)

= s q r \cdot 4 + s q r \cdot 2 tan^{2} (x)

= 4 s q r + 2 s q r tan^{2} (x)
