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

y^{2} + 2 x y \frac{d y}{d x}

Solution steps

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

Apply the Product Rule:

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

f = x, g = y^{2}

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

\frac{d x}{d x} = 1

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

= 1 \cdot y^{2} + 2 y \frac{d y}{d x} x

Simplify

= y^{2} + 2 x y \frac{d y}{d x}
