rozłóż na czynniki wielomiany metodą grupowania wyrazów:
c) W(x)=x^4-x^3-27x+27
b) W(x)=8x^4+24x^3+x+3
d) W(x)=125x^4-125x^3-8x+8

x⁴-x³-27x+27=x³[x-1]-27[x-1]=[x³-27][x-1]=
[x-3][x²+3x+9][x-1]
8x⁴+24x³+x+3=8x³[x+3]+[x+3]=[8x³+1][x+3]=[2x+1][4x²-2x+1][x+3]
125x⁴-125x³-8x+8=125x³[x-1]-8[x-1]=
[125x³-8][x-1]=[5x-2][25x²+10x+4][x-1]
