1. Answer:

   We have to find the zeroes

   First use trial and error method

   u can substitute 2

   if u substitude 2 in x the ans will be 0

   Hence (x-2) is one zero

   Now divide the given equation by ( x-2)

   We will get x2 – 1 as answer

   On factorising it we will get

   x2 – 1 ^2

   we get

   (x-1) and (x +1 )

   so ur factors r redy

2. Answer:

   x³-2x²-x+2

   x²(x-2)-1(x-2)

   (x-2)(x²-1)
