vereinfachen 16x^4-(y-2z)^2

Lösung

vereinfachen

16 x^{4} - (y - 2 z)^{2}

16 x^{4} - y^{2} + 4 yz - 4 z^{2}

Schritte zur Lösung

16 x^{4} - (y - 2 z)^{2}

(y - 2 z)^{2} : y^{2} - 4 yz + 4 z^{2}

= 16 x^{4} - (y^{2} - 4 yz + 4 z^{2})

- (y^{2} - 4 yz + 4 z^{2}) : - y^{2} + 4 yz - 4 z^{2}

= 16 x^{4} - y^{2} + 4 yz - 4 z^{2}

f a c t or 2 x^{2} - 4 x y + 2 y^{2}

s im pl i f y \frac{i - 2}{i - 1}

f a c t or x y + 7 y - 3 x - 21

- 1 (1 + 7 x) - 6 (- 7 - x) = 36

3 x = 33
