you have to set them equal to each other and find those points, y

_{1}=13x^{2}-x^{3}+x=x^{2}_{+36}=y_{2}-x

^{3}+12x^{2}-36. so there could be up to 3 separate points since it x^{3}. Then next step would be to factor this. Assuming you have three separate points the area would switch at the middle point. In this case there be one integral y_{1}-y_{2}from x point 1 to x point 2, and then another one y_{2}-y_{1}from x point 2 to x point 3. Good luck
