6x {}^{2}  - 5x + 3 - ( {3x}^{2}  + 8x - 4)

= 6 {x}^{2}  - 5x + 3 -  {3x}^{2}  - 8x + 4

= ( {6x}^{2}  -  {3x}^{2} ) + ( - 5x - 8x) + (3 + 4)

=  {3x}^{2}  - 13x + 7

Complete factorization of x^3 - 4x^2 + x - 4

x³ - 4x² + x - 4

= x²(x - 4) + (x - 4)

= (x² + 1)(x - 4).

Since the quadratic factor (x² + 1) is irreducible any further, this is our answer.
