erweitern (2+x)sqrt(9-x^2)

Lösung

erweitern

(2 + x) 9 - x^{2}

2 9 - x^{2} + x 9 - x^{2}

Schritte zur Lösung

(2 + x) 9 - x^{2}

= 9 - x^{2} (2 + x)

Wende das Distributivgesetz an:

a (b + c) = ab + a c

9 - x^{2} (2 + x) = 9 - x^{2} \cdot 2 + 9 - x^{2} x

= 9 - x^{2} \cdot 2 + 9 - x^{2} x

= 2 9 - x^{2} + x 9 - x^{2}
