$${\text{Second - order Linear differential equation}}$$

$$\eqalign{ & y''\left( t \right) + 9y\left( t \right) = 10 \cr & {\text{This differential equation is written in the form}} \cr & y''\left( t \right) + 0y'\left( t \right) + p\left( x \right)y\left( t \right) = f\left( x \right) \cr & {\text{And this is a second - order Linear differential equation}} \cr} $$
