1.14a²bc/-2ac²2.2x+8/x²-163.x/2a²b ÷(-2xb)4.x-1/1 + 1+x/15.a²-1/a + a²-1/3a+1 + 1-a²/2a+16.x²-2xy+y²/x²-y²,其中x=110,y=10.(先化简,再求值)7.已知(x-1)(x-2)/3x-4 = x-1分之A + x-2分之B,求实数A,B。8.(1-x)²/2x;1.-7ab/c2.(x-4)/23.-a^2*b/2*x^2*b4.2*x/(x^2-1)5.2*a/(a^2-1)6.(x+y)*(x-y)/(x-y)^2=(x+y)/(X-y)=1.27.(3x-4)/(x-1)(x-2)=1/(x-1)+2/(x-2) 所以 A=1 B=28.2/(1-x)(1/x-1)追问有点乱。。。追答标序号了
