Lösung

lo g_{2} (x^{2} + 5 x + 7) = 0

Lösung

x = - 2, x = - 3

Schritte zur Lösung

lo g_{2} (x^{2} + 5 x + 7) = 0

Wende die log Regel an

x^{2} + 5 x + 7 = 1

Löse

x^{2} + 5 x + 7 = 1 : x = - 2, x = - 3

ln(2x+1)+ln(-x+1)=0

ln (2 x + 1) + ln (- x + 1) = 0

log_{2}(x-2)=2-log_{2}(x+1)

lo g_{2} (x - 2) = 2 - lo g_{2} (x + 1)
