Let p(x) = 2x4 – 5x3 + 2x2 – x+ 2 firstly, factorise x2-3x+2.

Let p(x) = 2x4 – 5x3 + 2x2 – x+ 2 firstly, factorise x2-3x+2.Now, x2-3x+2 = x2-2x-x+2 [by splitting middle term]

Let p(x) = 2x4 – 5x3 + 2x2 – x+ 2 firstly, factorise x2-3x+2.Now, x2-3x+2 = x2-2x-x+2 [by splitting middle term]= x(x-2)-1 (x-2)= (x-1)(x-2)
