x^4-14x^3+48x^2+11x^2-94x+48
=x^2(x-6)(x-8)+(11x-6)(x-8)
=(x-8)(x^3-6x^2+11x-6)
=(x-8)(x^3-6x^2+9x+2x-6)
=(x-8)[x(x-3)^2+2(x-3)]
=(x-8)(x-3)(x^2-3x+2)
=(x-8)(x-3)(x-2)(x-1)
=x^2(x-6)(x-8)+(11x-6)(x-8)
=(x-8)(x^3-6x^2+11x-6)
=(x-8)(x^3-6x^2+9x+2x-6)
=(x-8)[x(x-3)^2+2(x-3)]
=(x-8)(x-3)(x^2-3x+2)
=(x-8)(x-3)(x-2)(x-1)

syms x
R1=simple(x^4-14*x^3+59*x^2-94*x+48)
R1 =
(x - 1)*(x - 2)*(x - 3)*(x - 8)
x^4-14x^3+59x^2-94x+48
=(x-1)(x^3-13x^2+46x-48)
=(x-1)(x-2)(x^2-11x+24)
=(x-1)(x-2)(x-3)(x-8)
