Find the value of m and n so that polynomial f(x) = x3 - 6x2 + mx - n  is  exactly divisible by (x-1) as well as (x-2) ?( PLS ANS ALL QUESTIONS URGENTLY)

CBSE IX Maths

Question Factorise: x3 + 13x2 + 32x + 20 Solution: Let p(x) = x3 + 13x2 + 32x + 20 p(-1) = -1 + 13 - 32 + 20 = -33 + 33 = 0 Therefore (x + 1) is a factor of p(x). On dividing p(x) by (x + 1) we get p(x)   (x + 1) = x2 + 12x + 20 Thus, x3 + 13x2 + 32x + 20 = (x + 1)(x2 + 12x + 20) = (x + 1) (x2 + 10x + 2x + 20) = (x + 1)[x(x + 10) + 2(x + 10)] = (x + 1) (x +2) (x + 10) Hence, x3 + 13x2 + 32x + 20 = (x + 1) (x +2) (x + 10). The above question is from the sureshot questions but I am not clear with the explanation.Please elaborate.Please reply urgently I have my Maths exam tomorrow
