-1, 3, -3

Step-by-step explanation:

I don't see the graph, but you can solve by factoring:

By the factor theorem, the solutions of f(x) are -1, 3, and -3.

they can both be solutions depends on the equation

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
