Answer:

Expand and then simplify.

Explanation:

  1. Begin by writing your brackets separately.
    #(4x-3)(4x-3)(4x-3)#

  2. Then expand and simplify two of the brackets.
    #(16x^2-12x-12x+9)(4x-3)#
    #(16x^2-24x+9)(4x-3)#

  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.
