We consider the equation $$ -(r(x) y'(x))'+q(x)y(x)=f(x),\quad x\in \mathbb R, $$ where $f\in L_p(\mathbb R)$, $p\in (1,\infty )$ and $$ r>0,\quad \frac {1}{r}\in L_1^{\rm loc}(\mathbb R),\quad q\in L_1^{\rm loc}(\mathbb R). $$ For particular equations of this form, we suggest some methods for the study of the question on requirements to the functions $r$ and $q$ under which the above equation is correctly solvable in the space $L_p(\mathbb R),$ $p\in (1,\infty ).$
