计算[36x-24x 12x]÷12x
计算:(x+y/x-y)÷(xy+x^2)

等于1/X*(X-Y)

分式计算 1-x/x²+x-2÷x²-1/x+2

(1-x)/(x²+x-2)÷[(x²-1)/(x+2)]=-(x-1)/[(x-1)(x+2)]÷[(x-1)(x+1)/(x+2)]=-1/(x+2)×(x+2)/[(x-1)

计算:(x^2-9分之1)÷(3x+1)

(x^2-1/9)÷(3x+1)=(x-1/3)(x+1/3)÷(3x+1)=(x-1/3)÷3=x/3-1/9

计算x

原式=x2+2x+4(x+2)2÷(x−2)(x2+2x+4)3(x+2)÷1(x+2)(x−2)=x2+2x+4(x+2)2•3(x+2)(x−2)(x2+2x+4)•(x+2)(x-2)=3.

计算:x

x2x−5+255−x=x2x−5-25x−5=x2−25x−5=(x+5)(x−5)x−5=x+5,故答案为:x+5.

计算:[x(-4X+3)+(X-2)x]÷(-X)

-[-4X^2+3X+X^2-2X]÷X-[-3x^2+x]]÷X-3x-1

(x²-6x+9)÷x+3分之x²-9x+18,计算

(x²-6x+9)÷x+3分之x²-9x+18,=(x²-6x+9)×(x+3)/(x²-9x+18)=(x-3)²(x+3)/[(x-3)(x-6)

计算:(1+2x−x+1x−2)÷x+4x

原式=[x(x−2)x(x−2)+2(x−2)x(x−2)-x(x+1)x(x−2)]•x(x−2)x+4=−(x+4)x(x−2)•x(x−2)x+4=-1.

计算 4x²-1/2-4x ÷ 4x²+4x+1 / x

解(4x²-1)/(2-4x)÷(4x²+4x+1)/x=(2x-1)(2x+1)/2(1-2x)×[x/(2x+1)²=-(2x+1)/2×[x/(2x+1)²

计算[x(x²-2x+3)-3x]÷2分之1x²

原式=x(x²-2x+3-3)×2/x²=x²(x-2)×2/x²=2x-4

计算:(3x-3/x²-1)÷(3x/x+1)-1/x-1

(3x-3/x²-1)÷(3x/x+1)-1/x-1=3(x-1)/[(x+1)(x-1)]÷[3x/(x+1)]-1/(x-1)=1/x-1/(x-1)=(x-1-x)/x(x-1)=-1

x²+1/x-6·x²-36/x³+x 计算

x²+1/x-6·x²-36/x³+x=(x²+1)/(x-6)*(x+6)(x-6)/x(x²+10=(x+6)/x再问:8x²y^4÷-

计算:2x/(x-2)(x+1)÷(1-x/x+1)-x²+2x/x²-4?

2x/(x-2)(x+1)÷(1-x/x+1)-x²+2x/x²-4?=2x/(x-2)(x+1)×(x+1)/(1-x)-x(x+2)/(x+2)(x-2)=2x/(x-2)(1

计算:[(3x-7)2-(x+5)2]÷(4x-24)

[(3x-7)2-(x+5)2]÷(4x-24),=(9x2-42x+49-x2-10x-25)÷(4x-24),=(8x2-52x+24)÷(4x-24),=4(2x-1)(x-6)÷4(x-6),

如何计算36除以x>12?

36÷x>12当x>0时,两边同时乘以x得12x3即:0

x³-x²/x²+x÷(x²-1) 计算

原式=x²(x-1)/x(x+1)÷(x+1)(x-1)=x(x-1)/(x+1)÷(x+1)(x-1)=x/(x+1)²

(x+24)*17/6=3(x-24) 计算,急

(x+24)*17/6=3(x-24)17x+17*24=18x-18*2418x-17x=18*24+17*24x=24*25x=600
