5) Multiply both sides by $\displaystyle x^2 -2 $ and then move all the terms to one side. There is a solution if the directrix is positive.

6) Assign variables b,d to BM and DN. Note that the area of a square is A = length squared = 36. So length of any one side is 6.

Now express the area of the triangles in terms of b and d, then compare the them. - Apr 29th 2010, 07:25 PMliloldadyo
