(\partial)/(\partial x)(x^2(y-x))

Lösung

\frac{\partial}{\partial x} (x^{2} (y - x))

2 x y - 3 x^{2}

Schritte zur Lösung

\frac{\partial}{\partial x} (x^{2} (y - x))

Behandle

y

als Konstante

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{2}, g = y - x

= \frac{\partial}{\partial x} (x^{2}) (y - x) + \frac{\partial}{\partial x} (y - x) x^{2}

\frac{\partial}{\partial x} (x^{2}) = 2 x

\frac{\partial}{\partial x} (y - x) = - 1

= 2 x (y - x) + (- 1) x^{2}

Vereinfache

2 x (y - x) + (- 1) x^{2} : 2 x y - 3 x^{2}

= 2 x y - 3 x^{2}
