\noindent In this talk we extend the discussion of black holes generalizing the classic Schwarzschild-\mbox{(anti-)de} Sitter solution to the study of additional classes of static spherically symmetric spacetimes admitted in the framework of a quadratic gravity. In detail we demonstrate the complexity of the field equations and their surprising simplification via suitable conformal metric ansatz and Bianchi identities. This procedure brings us to the ``one-line'' system of two autonomous ODEs which can be, with a great advantage, solved in terms of power series. Moreover, this enables us to naturally introduce various subclasses of static spherically symmetric geometries with any cosmological constant, e.g., black and worm holes, or so called 2-2-holes. We analyze the explicit forms of these solutions and discuss their important physical~properties.
