factor the following expressions completely 24x%5E3-81
------------
=3(8x^3 - 27)
=3*(2x-3)*(4x^2+6x+9)
----------------
%283a-c%29%5E3-c%5E3
= [(3a-c) -c]
= [3a-2c]
= [3a-2c]
That's it unless you factor the trinomial using imaginaries.
-----------------------------
solve the equation for xz=x%2Fk-m%2Fk+
z = (x-m)/k
zk = x-m
x = m+kz
