hey mate
here's ur answer
 {x}^{2}  - 3x + 2 \\  =  {x}^{2}  - x - 2x + 2 \\  = x(x - 1)  -  2(x - 1) \\  = (x - 2)(x - 1) \\
x= 1 or2
put the value of x in the equation
 {2x}^{4}  -  {5x}^{3}  +  {2x}^{2}  - x + 2 \\  = 2( {1})^{4}  - 5( {1})^{3}  + 2( {1})^{2}  - 1 + 2 \\  = 2 - 5 + 2 - 1 + 2 \\  = 6 - 6 \\  = 0
 = 2( {2})^{4}  - 5 {(2)}^{3}  + 2( {2)}^{2}  - 2 + 2 \\  = 32 - 40 + 8 \\  =  - 40 + 40 \\  = 0
yes ,the number is exactly divisible by x^2-3x+2

hope it helps
