Expand and then simplify.

Begin by writing your brackets separately.
$(4 x - 3) (4 x - 3) (4 x - 3)$ $(4x-3)(4x-3)(4x-3)$
Then expand and simplify two of the brackets.
$(16 x^{2} - 12 x - 12 x + 9) (4 x - 3)$ $(16x^2-12x-12x+9)(4x-3)$
$(16 x^{2} - 24 x + 9) (4 x - 3)$ $(16x^2-24x+9)(4x-3)$
Now expand your quadratic by the final bracket and then simplify.
$64 x^{3} - 96 x^{2} + 36 x - 48 x^{2} + 72 x - 27$ $64x^3-96x^2+36x-48x^2+72x-27$
$64 x^{3} - 144 x^{2} + 108 x - 27$ $64x^3-144x^2+108x-27$

Hope this has helped.
