WHAT do yo need?      Do you have values for 'x' ?    Do you need to find 'zeroes' ?  Do you need to factor these expressions?

2x^2  - 2  =  2 (x^2 -1)  = 2(x+1) (x - 1)

 

x^3 - 3x^2 + 3x + 2

 

We can write this as

 

x^3 - 2x^2 + x^2 + 3x + 2  =

 

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

 

Notice that no factor is common....so......this polynomial is irreducible

 

 

 

cool cool cool
