To factor #4x^3-9x+2#, you'll need to find its zeros.

Explanation:

Use whatever techniques you have available (Cardano's method, Newton's method, graphing or other technology, etc), to find or approximate the roots of
#4x^3-9x+2=0#

Call them #z_1, z_2,z_3#

Then #4x^3-9x+2 = 4(x-z_1)(x-z_2)(x-z_3)#
