6x^3-6x^2-(5x^2-x-4)=
6x^2(x-1)-(x-1)(5x+4)=
(x-1)(6x^2-5x-4)=
(x-1)(3x-4)(2x+1)
6x^2(x-1)-(x-1)(5x+4)=
(x-1)(6x^2-5x-4)=
(x-1)(3x-4)(2x+1)

6x^3-11x^2+x+4
=6x^3-6x^2-5x^2+5x-4x+4
=6x^2(x-1)-5x(x-1)-4(x-1)
=(x-1)(6x^2-5x-4)
=(x-1)(2x+1)(3x-4)
=6x^3-6x^2-5x^2+5x-4x+4
=6x^2(x-1)-5x(x-1)-4(x-1)
=(x-1)(6x^2-5x-4)
=(x-1)(2x+1)(3x-4)
