Answer 2

Answer:

(x-1)(x +3)(x - 4)

Step-by-step explanation:

I think your question, is to factorise, p(x) = x³-2x²-11x+12  (check your question)

so, given,

p(x) = x³-2x²-11x+12

      = x³-x²-x²-12x+x+12

      = x³-x² -x²+x -12x+12

      = x²(x-1) -x(x-1) -12(x-1)

      = (x-1) [ x² -x -12 ]

      = (x-1) [ x² +3x -4x -12 ]

      = (x-1) [ x(x +3) -4(x +3) ]

      = (x-1) [ (x +3)(x - 4) ]

      = (x-1)(x +3)(x - 4)
