We will use the Descartes` rule of signs and see how many times the signs change from positive to negative and from negative to positive from one term to the next ( two consecutive terms are with different signs ).
In this case it is 4 times ( +7x13 to -12x9, -12x9 to +16x5, +6x5 to -23 x and finally -23x to +42 ).

Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.
