Diferencia de un polígono cóncavo y otro convexo

Hola no hablo espanol puedes traducir. Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For apolygon to be convex, all of its interior angles must be less than 180 degrees. ... Below in Part A are some convexpolygons, and in Part B, some concavepolygons.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
