Two students, jennifer and jamal, factored the trinomial 6x2 − 3x − 9. jamal factored it as 3(2x − 3)(x + 1) and jennifer factored it as (2x − 3)(3x + 3). indicate which student factored the trinomial completely and which student did not, and explain why.

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
