3x+5/(x+2)(x+3)=A/(x+2)+B/x+3,求(3A+B)的2008次方3x+5/(x+2)(x+3)=A/(x+2)+B/x+3,求(3A+B)的2008次方
3x+5/(x+2)(x+3)=A/(x+2)+B/x+3,求(3A+B)的2008次方
3x+5/(x+2)(x+3)=A/(x+2)+B/x+3,求(3A+B)的2008次方
3x+5/(x+2)(x+3)=A/(x+2)+B/x+3,求(3A+B)的2008次方3x+5/(x+2)(x+3)=A/(x+2)+B/x+3,求(3A+B)的2008次方
3x+5/(x+2)(x+3)=A/(x+2)+B/x+3=(Ax+3A+BX+2B)/(x+2)(x+3)
(A+B)=3
3A+2B=5
A=-1
B=4
(3A+B)的2008次方
=(-3+4)的2008次方
=1
x^2-6x+5= A(x-2)(x-3)B(x-6)(x+1)

( A/X-5 ) + ( B/X+2 ) = 5X-4/X^2-3X-10 ^-^
5x+15/x^2+x-6=A/x-2+B/x-3
已知集合A={X|2x-3/x+5
已知集合A={x|(2x-3)/(x+5)
已知集合A={x|(2x-3)/(x+5)
已知集合A={X|2x-3/x+5
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
x-2x+3x-4x+5x.+99x-100x=25求解
