erweitern T2^2(T^2-1.9044=2405.6014)

Lösung

erweitern

T 2^{2} (T^{2} - 1.9044 = 2405.6014)

4 T^{3} - 7.6176 T = 2405.6014

Schritte zur Lösung

T \cdot 2^{2} (T^{2} - 1.9044 = 2405.6014)

= 2^{2} T (T^{2} - 1.9044 \cdot 2405.6014 =)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = T \cdot 2^{2}, b = T^{2}, c = 1.9044 = 2405.6014

T \cdot 2^{2} T^{2} - T \cdot 2^{2} \cdot 1.9044 = 2405.6014

2^{2} T^{2} T - 2^{2} \cdot 1.9044 T = 2405.6014
