Subract (2x^(3)+4x^(2)-9x) from (-5x^(3)+4x-12)
-------------------------------------------------
(-5x^(3)+4x-12) - (2x^(3)+4x^(2)-9x)
-----------------
-5x^3 + 4x - 12 - 2x^3 - 4x^2 + 9x
---------------------------------------------
= -7x^3 -4x^2 + 13x -12
---------------------------------------------
