Divide 12t6 8t8 2t3 6t3 8t8 12t6 4t5 6t2 8t4 6t3 45 Div
     Divide (12t^6 - 8t^8)  (2t^3)  6t^3 - 8t^8  12t^6 - 4t^5  6t^2 - 8t^4  6t^3 - 4^5  Divide (10d^9 - 6d^8 + 4d^5)  (2d^3)  5d^3 - 3d^5 + 2d^2  5d^6 - 6d^8 = 4d^5   
  
  Solution
13. (12t6-8t8)/2t3 = 4t6(3 -2t2)/2t3 = 2t3( 3 -2t2) = 6t3 -4t5 ( if t 0)
14. (10d9 -6d8+ 4d5)/2d3 = 2d3(5d6 - 3d5 + 2d2 )/2d3 = 5d6 - 3d5 + 2d2 ( if d 0)
