分解因式:(x-1)^2-(y+2)^2
分解因式:(x-1)^2-(y+2)^2

分解因式:(x-1)^2-(y+2)^2
(x-1)^2-(y+2)^2
=[(x-1)+(y+2)][(x-1)-(y+2)]
=(x+y+1)(x-y-3)

(x-1+y+2)(x-1-y-2)
=(x+y+1)(x-y-3)

(x-1)^2-(y+2)^2
=(x-1+y+2)(x-1-y-2)
=(x+y+1)(x-y-3)

(x-1)^2-(y+2)^2
=(x-1+y+2)(x-1-y-2)
=(x+y+1)(x-y-3)

(x-1)^2-(y+2)^2
=(x-1+y+2)(x-1-y-2)
=(x+y+1)(x-y-3)
