alr straight to the point here: find each of the two areas bounded by the curve y=x^3 -4x and y=x^2 +2x. at first this seemed straight forward, find the critical points, the graph behaviour, and the intersection of the two curves to get both areas. But an added instruction was to quote "solve in two ways". I dont think i can solve using horizontal strips if thats what that means since it wont touch both curves at some points. So what would be the second way?

a1 would be 16/3 sq units and a2=63/4 sq units is what i got

They probably just meant to express the integrand as an absolute value as an alternative and do it.
They both give you the same result

that sounds reasonable, thanks
