怎么分解10a(x-y)-5b(y-x)
怎么分解10a(x-y)-5b(y-x)

怎么分解10a(x-y)-5b(y-x)
10a(x-y)-5b(y-x)
=10a(x-y)+5b(x-y)
=(x-y)(10a+5b)
=5(x-y)(2a+b)

5(2a+b)(x-y)?

10a(x-y)-5b(y-x)
=-10a(y-x)-5b(y-x)
=-(y-x)(10a+5b)

原式=10ax-10ay-5by+5bx
=x(1oa+5b)-y(10a+5b)
=(x-y)(10a+5b)

哦也,不会做

(10a+5b)x-(10a-5c)y 还有你要的分解是什么啊?分解公因式?
(10a+5b)(x-y) 你说的应该是第二个……

10a(x—y)—5b(y—x)
=10a(x—y)+5b(x—y)
=(10a+5b)(x—y)
=2(5a+b)(x—y)
