若a/(x+1)+b/(x-5)=3x/(x+1)(x+5),求实数a,b的值答案为a=1,b=2 求具体过程` 谢谢

x^2-6x+5= A(x-2)(x-3)B(x-6)(x+1) 函数f(x)=x2+mx+n,A{x|f(x)=x},B{x|f(x-1)>x+5},若A={3},求集合B? 若(ax+b)/(x-3)=(5x)/(x-3)-(3x-1)/(x-3),则a= b= 若A={x|(1/2)^(x+2)(x-3)>1}B={x|(3a-x)/(x-a) 若A=3x^2 -x-1,B=4x^2-5x+4,则A,B大小 若代数式x^4-(a-1)x^3+(b+3)x+5x^2-ax不含x^3和x项,则a=(),b=() f(x)=(3a-1)x+b-a,x属于[0,1],若f(x) （1） x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8(2) 已知x+3/(x-2)^2=A/x-2 + B/(x-2)^2 ,求A和B的值. 若x+4/x²+5x+6=A/x+2+B/x+3,A=?,B=? 若x+4/x²+5x+6=A/x+2+B/x+3,A=?,B=? 若3x+7/（x-1)(x-2)=A/x-1+B/x-2 则A= B= 若(x+1)(x-1)/x-3=x+1/A+x-1/B,求A、B、的值 A/x+1-B/ x-3=x+5/(x+1)(x-3) .求A=?B=? 若(x-3)/(x*x-1)=A/(x+1)-B/(x-1),求A.B的值 已知x+5/(x+1)(x-3)=a/x+1+b/x-3,求整式A,B的值 已知x+5/(x+1)(x-3)=A/x+1-B/x-3,求A,B （x+5）/[(x+1)(x-3)]=A/(x+1)-B/(x-3),求A、B 若A/x+2+B/x+3=7x+1/x²-x-6,求A,B
