erweitern (2x)(ln(x)-x=0)

Lösung

erweitern

(2 x) (ln (x) - x = 0)

2 x ln (x) - 2 x^{2} = 0

Schritte zur Lösung

(2 x) (ln (x) - x = 0)

= (2 x) (ln (x) - 0 = x)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = (2 x), b = ln (x), c = x = 0

(2 x) ln (x) - (2 x) x = 0

ln (x) (2 x) - x (2 x) = 0
