The given differential equation is$ydy+\left(x{y}^2-8x\right)dx=0$ with boundaries y = 3 when x = 1.

A differential equation is a mathematical equation that connects one or more unknown functions with their derivatives. The study of differential equations primarily entails looking at their solutions (the set of functions that satisfy each equation) and characteristics.

Separate the variables in $ydy+\left(x{y}^2-8x\right)dx=0$ and keep y on one side and x on the other.

$$\begin{gathered} ydy+\left(x{y}^2-8x\right)dx=0 \\ ydy=-x\left(y^2-8\right)dx \\ \frac{y}{y^2-8}dy=-xdx \end{gathered}$$
