A/x+1-B/x-3=x+5/(x+1)(x-3).求A=?B=?A/x+1-B/x-3=x+5/(x+1)(x-3).求A=?B=?A/x+1-B/x-3=x+5/(x+1)(x-3).求A=?B
A/x+1-B/ x-3=x+5/(x+1)(x-3) .求A=?B=?
A/x+1-B/ x-3=x+5/(x+1)(x-3) .求A=?B=?
A/x+1-B/ x-3=x+5/(x+1)(x-3) .求A=?B=?
A/(x+1)-B/(x-3)=(x+5)/(x+1)(x-3)
[A(x-3)-B(x+1)]/(x+1)(x-3)=(x+5)/(x+1)(x-3)
[(A-B)x-3A-B]/(x+1)(x-3)=(x+5)/(x+1)(x-3)
A-B=1
-3A-B=5
A=-1,B=-2
ax-3a-bx-b=x+5
a-b=1
b+3a=-5
a=-1
b=-2
x^2-6x+5= A(x-2)(x-3)B(x-6)(x+1)
（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.
已知集合A｛x|x>5｝,B=｛x|x>-1｝,则A∩B等于 A.｛x|x>5｝,B.｛x|x>-1｝,C｛x|-1
A/x+1-B/ x-3=x+5/(x+1)(x-3) .求A=?B=?
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
设函数f(x)={a/x+b/(x²-x) x>1{x x
(3x+2)(-x^6+3x^5)+(3x+2)(-2x^6+x^5)+(x+1)(3x^6-4x^5)=( )A(3x^6-4x^)(2x+1)B(3x^6-4x^5)(2x+3)C-(3x^6)(2x+1)B-(3x^6)(2x+3)
A/x-1+B/x+2+C/x-3=x²+2x+5/(x-1)(x+2)(x-3)求ABC的值
设a=(x^2+6x,5x),b=(1/3x,1-x)x∈[0,9] 求f(x)=a*b的表达式
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?
5x+1=A(x-2)+B(x-1)
若(ax+b)/(x-3)=(5x)/(x-3)-(3x-1)/(x-3),则a= b=
( A/X-5 ) + ( B/X+2 ) = 5X-4/X^2-3X-10 ^-^
4x+1/(x-2)(x-5)=a/x-2+b/x-5
5x+15/x^2+x-6=A/x-2+B/x-3
设集合A={x|x>3},B={x| x-1/x-4
