erweitern (2)(3s+1)(s+1/16)

Lösung

erweitern

(2) (3 s + 1) (s + \frac{1}{16})

6 s^{2} + \frac{19 s}{8} + \frac{1}{8}

Schritte zur Lösung

(2) (3 s + 1) (s + \frac{1}{16})

Apply rule:

(a) = a

(2) = 2

= 2 (3 s + 1) (s + \frac{1}{16})

Apply FOIL method

(3 s + 1) (s + \frac{1}{16}) : 3 s^{2} + \frac{19 s}{16} + \frac{1}{16}

= 2 (3 s^{2} + \frac{19 s}{16} + \frac{1}{16})

Wende das Distributivgesetz an:

m (a + b + c) = ma + mb + m c

2 (3 s^{2} + \frac{19 s}{16} + \frac{1}{16}) = 2 \cdot 3 s^{2} + 2 \cdot \frac{19 s}{16} + 2 \cdot \frac{1}{16}

= 2 \cdot 3 s^{2} + 2 \cdot \frac{19 s}{16} + 2 \cdot \frac{1}{16}

Vereinfache

2 \cdot 3 s^{2} + 2 \cdot \frac{19 s}{16} + 2 \cdot \frac{1}{16} : 6 s^{2} + \frac{19 s}{8} + \frac{1}{8}

= 6 s^{2} + \frac{19 s}{8} + \frac{1}{8}
