回答1:

(x²+2x)²-(2x+4)²
=(x²+2x+2x+4)(x²+2x-2x-4)
=(x²+4x+4)(x²-4)
=(x+2)³(x-2)

不懂可追问,有帮助请采纳,谢谢!

回答2:

(1)(x²+2x)²-(2x+4)²

=[(x²+2x)-(2x+4)][(x²+2x)+(2x+4)]
=(x²-4)(x²+4x+4)
=(x-2)(x+2)(x+2)²
=(x-2)(x+2)³

回答3:

(x²+2x)²-(2x+4)²
=(x²+2x+2x+4)(x²+2x-2x-4)
=(x²+4x+4)(x²-4)
=(x+2)²(x+2)(x-2)
=(x+2)³(x-2)

回答4:

(x^2+2X+2X+4)(X^2+2X-2X-4)
=(X^2+4X+4)(X^2-4)
=(x+2)^2(x+2)(x-2)
=(x+2)^3(x-2)

回答5:

原式=x²(x+2)²-4(x+2)²
=(x+2)²(x²-4)
=(x+2)³(x-2)

回答6:

原式=x^2(x+2)^2-4(x+2)^2
=(x+2)^2*(x^2-4)
=(x+2)^3*(x-2)
