(x-1/x²+6x+9)÷(x²-1/x+3)=(x+1/2)
(x-1/x²+6x+9)÷(x²-1/x+3)=(x+1/2)
若x=1/x,则(x²2-6x+9)/(x-3)÷(x+3)/(x²+6x+9)的值是
当X=1/X时 求分式 X²-6X+9/X-3 ÷ X+3/X²+6X+9 的值
先化简,再求值:1/x+1-3-x/x²-6x+9÷x²+x/x-3,其中x=根号2.
x^2-x/x+1÷x/x+1 ;x^2+6x+9/x^2-9÷x+2/x-3;2/a÷4/a
x(2-1/x)+x/(x^2-2x)÷(3-x)/(x^2-4)2.2/3+x/(3x-1)=1/9x-3
当x=9/2时,求(x^2+7x+10)/(x^2+6x+5)×(x^3+1)/(x^2+4x+4)÷(x^2-x+1)/(x+2)

(1-x/3-x)^2÷(x^2-6x+9/9-x^2)*1/x^2-2x+1
(9x³-6x²-5x+2)÷(3x-1)=?
1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/(x^2-5x+6)+(x^2-3x+8)/(x^2-4x+3)2.{(x^2)/(x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{(x^2/x^2+y^2)^2}
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
化简:【x-3/x+3 + 6x/x^2-9】÷ 1/x^2-9
(x-3/x+3+6x/x²-9)÷1/x²-9化简就行
先化简,再求值:9-x²/x²+6x+9÷x²-3x/2x+6-2/x²-x,其中x=6
计算:(1)/(x-3)÷(x+2)/(x^2-9)-(1)/(x^2+5x+6)
2/x+1+3/x-1=6/x²-1 4-x/x-4+1/4-x=1 不等组5x-2>3(x+1)x-2大于等于18-x 化简计算(x²/x-3-9/x-3)÷1/x²+3x (x=1/3)
