Answer 1

Answer:

(x-1)(x+1)(x-2)

Step-by-step explanation:

first multiply first and the last term ,

here it is 2 so the factors of 2 are +-1 ,+-2

by hidden trial method check which of these is a factor of p(x) .

here it is (x-1) divide p(x) by (x-1) ( long division )

factorise the quotient , which is x^2-x-2

this will have 2 factors and x-1 is the 3rd factor
