Answer: Hello!
A second order differential equation has the next shape:

where p(t), q(t) and g(t) are functions of t, that can be constant numbers for example.
And is called homogeneus when g(t) = 0, so you have:

Then a second order differential equation is homogeneus ef every term involve either y or the derivatives of y.
Answer: y=4
Step-by-step explanation:
9/4y-12=1/4y-4+12
+12. +12
9/4y=1/4y+8
-1/4y -1/4y
2y/2=8/2
y=4
