derivative of x^2-3xy+y^2

Solution

\frac{d}{d x} (x^{2} - 3 x y + y^{2})

Solution

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

Solution steps

\frac{d}{d x} (x^{2} - 3 x y + y^{2})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

\frac{d}{d x} (3 x y) = 3 (y + x \frac{d y}{d x})

\frac{d}{d x} (y^{2}) = 2 y \frac{d y}{d x}

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