erweitern (x-((3+sqrt(2))/2))(x-((3-sqrt(2))/2))

Lösung

erweitern

(x - (\frac{3 + 2}{2})) (x - (\frac{3 - 2}{2}))

x^{2} - 3 x + \frac{7}{4}

Schritte zur Lösung

(x - (\frac{3 + 2}{2})) (x - (\frac{3 - 2}{2}))

Vereinfache

(x - (\frac{3 + 2}{2})) (x - (\frac{3 - 2}{2})) : (x - \frac{3 + 2}{2}) (x - \frac{3 - 2}{2})

= (x - \frac{3 + 2}{2}) (x - \frac{3 - 2}{2})

Apply FOIL method

(x - \frac{3 + 2}{2}) (x - \frac{3 - 2}{2}) : x^{2} - 3 x + \frac{7}{4}

= x^{2} - 3 x + \frac{7}{4}

e x p an d (4 + 7) (6 + 5)

e x p an d e^{- \frac{1}{( x + h ) ^{2}}} - e^{- \frac{1}{x ^{2}}}

e x p an d (- 2, - 6, - 7) l e f t (- 86, - 116, 34)

e x p an d (1 + z + \frac{z ^{2}}{2})^{4}

e x p an d (16 u^{3} + v^{3})^{2} + 144 u^{8} v^{4} + 1
