3x/6x^2z =1/2xz
a+b/a^2-b^2=(a+b)/(a+b)(a-b)=1/(a-b)
x^2+2x+1/x^2+x=(x+1)²/x(x+1)=(x+1)/x
3x-6/x^2-4x+4=3(x-2)/(x-2)²=3/(x-2)
y-x/x^2-y^2=-(x-y)/(x+y)(x-y)=-1/(x+y)
2x^2-10x/x^2-10x+25=2x(x-5)/(x-5)²=2x/(x-5)
a+b/a^2-b^2=(a+b)/(a+b)(a-b)=1/(a-b)
x^2+2x+1/x^2+x=(x+1)²/x(x+1)=(x+1)/x
3x-6/x^2-4x+4=3(x-2)/(x-2)²=3/(x-2)
y-x/x^2-y^2=-(x-y)/(x+y)(x-y)=-1/(x+y)
2x^2-10x/x^2-10x+25=2x(x-5)/(x-5)²=2x/(x-5)

x^2-6x+5= A(x-2)(x-3)B(x-6)(x+1)
已知a(x*x+x-c)+b(2x*x-x-2)=7x*x+4x+3x.求a,b,c的值
若多项式2x*x*x*x-3x*x*x+ax*x+7x+b能被x*x+x-2整除,求a:b
x²+x-6分之3x+4=x-2分之A + x+3分之B,求A,B
x^2-x/x+1÷x/x+1 ；x^2+6x+9/x^2-9÷x+2/x-3；2/a÷4/a

5x+15/x^2+x-6=A/x-2+B/x-3
( A/X-5 ) + ( B/X+2 ) = 5X-4/X^2-3X-10 ^-^
