4x^4-16x^3+7x^2+16x+4=0

Lösung

4 x^{4} - 16 x^{3} + 7 x^{2} + 16 x + 4 = 0

Lösung

x = 2, x = - \frac{1}{2}, x = \frac{5 + 41}{4}, x = \frac{5 - 41}{4}

x = 2, x = - 0.5, x = 2.85078 \dots, x = - 0.35078 \dots

Schritte zur Lösung

4 x^{4} - 16 x^{3} + 7 x^{2} + 16 x + 4 = 0

Faktorisiere

4 x^{4} - 16 x^{3} + 7 x^{2} + 16 x + 4 : (x - 2) (2 x + 1) (2 x^{2} - 5 x - 2)

(x - 2) (2 x + 1) (2 x^{2} - 5 x - 2) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x - 2 = 0 or 2 x + 1 = 0 or 2 x^{2} - 5 x - 2 = 0

Löse

x - 2 = 0 : x = 2

Löse

2 x + 1 = 0 : x = - \frac{1}{2}

Löse

2 x^{2} - 5 x - 2 = 0 : x = \frac{5 + 41}{4}, x = \frac{5 - 41}{4}

Die Lösungen sind

x = 2, x = - \frac{1}{2}, x = \frac{5 + 41}{4}, x = \frac{5 - 41}{4}
