erweitern (2-8x^2-2x)-(7x^3+3x=5x^2)

Lösung

erweitern

(2 - 8 x^{2} - 2 x) - (7 x^{3} + 3 x = 5 x^{2})

- 7 x^{3} - 8 x^{2} - 5 x + 2 = 5 x^{2}

Schritte zur Lösung

(2 - 8 x^{2} - 2 x) - (7 x^{3} + 3 x = 5 x^{2})

= (2 - 8 x^{2} - 2 x) - (7 x^{3} + 3 \cdot 5 = x^{2} x)

- (7 x^{3} + 3 x = 5 x^{2}) : - 7 x^{3} - 3 x = 5 x^{2}

(2 - 8 x^{2} - 2 x) - 7 x^{3} - 3 x = 5 x^{2}
