log_{4}(x^2-5x+2)=2

Lösung

lo g_{4} (x^{2} - 5 x + 2) = 2

x = 7, x = - 2

Schritte zur Lösung

lo g_{4} (x^{2} - 5 x + 2) = 2

Wende die log Regel an

x^{2} - 5 x + 2 = 16

Löse

x^{2} - 5 x + 2 = 16 : x = 7, x = - 2

x = 7, x = - 2

0 = lo g_{2} (x - 2)

ln (12 x^{2} + 12) - 3 = 0

lo g_{9} (x) + lo g_{9} (x + 2) - \frac{1}{2} = 0

lo g_{4} (4 x - 8) = 3

9 = lo g_{3} (x - 272) + 3
