先就这些,拜托各位了,直接给化解出来的答案就好了
xy-2x+3y-6=(x+3)(y-2)
5a^2+6ab-8b^2=(a+2b)(5a-4b)
3(x-y)^2+11(y-x)-4 =(x-y+4)(3x-3y-1)
x^2-y^2+2x+1 =(x+1-y)(x+1+y)
8a^3-b^3-12a^2b+6ab^2=(2a-b)^3
(x^2+x)^2-14x^2-14x+24=(x-1)(x+2)(x-3)(x+4)
(x-3)(y-2)
(x+3)(y-2) (5a-4b)(a+2b) (3x-3y+1)(x-y-4)
( x+y+1)(x-y+1) (2a-b)^3 (x-1)(x+2)(x-3)(x+4)
