24x%5E3y-8xy%5E2
8xy%2A%283x%5E2+-+y%5E2%29
------------------
%2836x%5E2+-+49y%5E2%29
= (6x - 7y)*(6x + 7y)
--------------
(x^2 + 5x-24)
= (x + 8)*(x - 3)
------------------
16x%5E2+-+24xy+%2B+9y%5E2+
= %284x+-+3y%29%5E2
----------------
5r%5E3+-+5
= 5%28r%5E3-1%29
= 5%2A%28r-1%29%2A%28r%5E2+%2B+r+%2B+1%29
