Expand and then simplify.
Explanation:
-
Begin by writing your brackets separately.
#(4x-3)(4x-3)(4x-3)# -
Then expand and simplify two of the brackets.
#(16x^2-12x-12x+9)(4x-3)#
#(16x^2-24x+9)(4x-3)# -
Now expand your quadratic by the final bracket and then simplify.
#64x^3-96x^2+36x-48x^2+72x-27#
#64x^3-144x^2+108x-27#
Hope this has helped.
