1.x^4-2x^3-8x+16
2.144(x2-1)x^2-100x^2
3.(x^2+6x+6)^2+x^2+6x+4

1.x^4-2x^3-8x+16
=x³(x-2)-8(x-2)
=(x-2)(x³-8)
=(x-2)²(x²+2x+4)
2.144(x2-1)x^2-100x^2
=x²(144x²-144-100)
=x²(12x+2√61)(12x-2√61)
3.(x^2+6x+6)^2+x^2+6x+4
=[(x^2+6x+4)+2]^2+(x^2+6x+4)
=((x^2+6x+4)²+4((x^2+6x+4)+4+(x^2+6x+4)
=((x^2+6x+4)²+5(x^2+6x+4)+4
=(x^2+6x+4+1)(x^2+6x+4+4)
=(x+1)(x+5)(x+2)(x+4)
