expand 2xy-9x^2+(2y+x^2+1)(dy)/(dx)

expand

2 x y - 9 x^{2} + (2 y + x^{2} + 1) \frac{d y}{d x}

2 x y - 9 x^{2} + 2 y \frac{d y}{d x} + x^{2} \frac{d y}{d x} + \frac{d y}{d x}

Solution steps

2 x y - 9 x^{2} + (2 y + x^{2} + 1) \frac{d y}{d x}

Expand

\frac{d y}{d x} (2 y + x^{2} + 1) : 2 y \frac{d y}{d x} + x^{2} \frac{d y}{d x} + \frac{d y}{d x}

= 2 x y - 9 x^{2} + 2 y \frac{d y}{d x} + x^{2} \frac{d y}{d x} + \frac{d y}{d x}
