因式分解(x2-y2)-(x-y)2快
因式分解(x2-y2)-(x-y)2
快
因式分解(x2-y2)-(x-y)2快
解
(x²-y²)-(x-y)²
=(x-y)(x+y)-(x-y)²
=(x-y)[(x+y)-(x-y)]
=(x-y)×2y
=2y(x-y)
=(x+y)(x-y)-(x-y)^2=(x-y)(x+y-x+y)=2y(x-y)
2是平方把
原式=(x+y)(x-y)-(x-y)²
=(x-y)【(x+y)-(x-y)】
=2y(x-y)
(x²-y²)-(x-y)²
=(x-y)(x+y)-(x-y)²
=(x-y)[x+y-(x-y)]
=(x-y)(x+y-x+y)
=2y(x-y)
