For this question, I see that xux + yuy is Linear Homogenous. However, looking at zuz, I believe that the most precise answer for this question is Linear Homogenous as well right?

Part $u$ is also linear and homogeneous$. Thus the *correct and precise answer* is linear homogeneous.

$$u_{t} + u_{xxxx} + u=0 \tag{1.2.16}$$

I understand that the first part of the equation ( $u_t +u_{xxxx}$) is definitely Linear Homogenous. However, the $u$ in the last part is confusing me and I am stuck between two answers - linear homogenous or semi linear?
