平方差公式分解因式 过程

Question

过程啊。。不要简啊，
1.x^6-1/4y^4
2.(x+y)^2-(x-z)^2

Answer 1

1.x^6-1/4y^4
=(X^3)^2-(1/2Y^2)^2
=(X^3+1/2Y^2)(X^3-1/2Y^2)
2.(x+y)^2-(x-z)^2
=(X+Y+X-Z)(X+Y-X+Z)
=(2X+Y-Z)(Y+Z)

Answer 2

1.x^6-1/4y^4
=(x^3+1/2y^2)(x^3-1/2y^2)

2.(x+y)^2-(x-z)^2
=[(x+y)+(x-z)][(x+y)-(x-z)]
=(2x+y-z)(y+z)本回答被提问者采纳

Answer 3

1.(x^3-1/2y^2)(x^3+1/2y^2)
2.[(x+y)+(x-z)][(x+y)-(x-z)]=(x+y+x-z)(x+y-x+z)=(2x+y-z)(y+z)

Answer 4

自己多好好看看书吧！
