a/x+2与b/x-2等于4x/x2-1,则a= ,b=a/x+2与b/x-2的和等于4x/x2-1,则a= ,b=

a/x+2与b/x-2等于4x/x2-1,则a= ,b=a/x+2与b/x-2的和等于4x/x2-1,则a= ,b=
a/x+2与b/x-2等于4x/x2-1,则a= ,b=
a/x+2与b/x-2的和等于4x/x2-1,则a= ,b=

a/x+2与b/x-2等于4x/x2-1,则a= ,b=a/x+2与b/x-2的和等于4x/x2-1,则a= ,b=
a=2 b=2

a(x-2)=b(x+2)
化简(a-b)(x-2)=0
因为分母上有x-2 所以x-2不等于0
所以a-b=0 a=b
交叉相乘得 4x^2+8x=(x^2-1)a
4x^2-8x=(x^2-1)b
所以4x^2+8x=4x^2-8x 16x=0 x=0 所以a=b=0
