erweitern (x+2)(x-2)(x+17/10)(x-17/10)

Lösung

erweitern

(x + 2) (x - 2) (x + \frac{17}{10}) (x - \frac{17}{10})

x^{4} - \frac{689 x ^{2}}{100} + \frac{289}{25}

Schritte zur Lösung

(x + 2) (x - 2) (x + \frac{17}{10}) (x - \frac{17}{10})

Schreibe

(x + 2) (x - 2) (x + \frac{17}{10}) (x - \frac{17}{10})

um:

(x^{2} - 4) (x + \frac{17}{10}) (x - \frac{17}{10})

= (x^{2} - 4) (x + \frac{17}{10}) (x - \frac{17}{10})

Apply Difference of Two Squares

(x + \frac{17}{10}) (x - \frac{17}{10}) : x^{2} - \frac{289}{100}

= (x^{2} - 4) (x^{2} - \frac{289}{100})

Apply FOIL method

(x^{2} - 4) (x^{2} - \frac{289}{100}) : x^{4} - \frac{689 x ^{2}}{100} + \frac{289}{25}

= x^{4} - \frac{689 x ^{2}}{100} + \frac{289}{25}
