化简(ac)/(a-c)-(bc)/(a-b)
化简(ac)/(a-c)-(bc)/(a-b)
化简(ac)/(a-c)-(bc)/(a-b)
(ac)/(a-c)-(bc)/(a-b)
= (acx(a-b) - bcx(a-c))/((a-c)(a-b))
= (ca^2 - abc - abc + b -c^2)/((a-c)(a-b))
= (cx(a^2 - 2ab -b^2))/((a-c)(a-b))
= (cx(a-b)^2)/((a-c)(a-b))
=（c(a-b)）/ (a-c)
解(ac)/(a-c)-(bc)/(a-b)
= (acx(a-b) - bcx(a-c))/((a-c)(a-b))
= (ca^2 - abc - abc + b -c^2)/((a-c)(a-b))
= (cx(a^2 - 2ab -b^2))/((a-c)(a-b))
= (cx(a-b)^2)/((a-c)(a-b))
=（c(a-b)）/ (a-c)
