1、(x²-1)²+6(1-x²)+92、a³+6a²+11a+6

1、(x²-1)²+6(1-x²)+92、a³+6a²+11a+6
1、(x²-1)²+6(1-x²)+9
2、a³+6a²+11a+6

1、(x²-1)²+6(1-x²)+92、a³+6a²+11a+6
1,(x²-1)²+6(1-x²)+9
=(x²-1)²-6(x²-1)+9
=(x²-1-3)²
=(x+2)^2(x-2)^2
2,a³+6a²+11a+6
=a^3+6a^2+9a+2a+6
=a(a^2+6a+9)+2(a+3)
=a(a+3)^2+2(a+3)
=(a+3)[a(a+3)+2]
=(a+3)(a^2+3a+2)
=(a+3)(a+1)(a+2)

1、(x²-1)²+6(1-x²)+9
=(x²-1)²-6(x²-1)+9
=[(x²-1)-3]²
=(x²-4)²

(x²-1)²+6(1-x²)+9=(x²-1)²-6(x²-1)+9
=(x²-1-3)²
a³+6a²+11a+6
=

1、(x²-1)²+6(1-x²)+9
=(x²-1)²-6(x²-1)+9
=[(x²-1)-3]²
=(x²-4)²
=(x+2)²(x-2)²
2、a³+6a²+11a+6
=(a+3)(a²+3a+2)
=(a+3)(a+2)(a+1)

1、=(x²-1)²-6(x²-1)+9=(x²-1-3)²=(x²-4)²
2、a³+6a²+11a+6=a³+a²+5a²+5a+6a+6=a²(a+1)+5a(a+1)+6(a+1)=(a+1)(a²+5a+6)=(a+1)(a+2)(a+3)

1原式=(1-x2)2+6(1-x2)+3乘3
=(1-X2+3)的平方
