再问:请问经过和结果怎么写?再答:
你可以发个图给个题目吗,这样不知那些是分子,那些是第二项a再问:好吧再问:再答:再答:图中的第二题,你们是一个班的吧?问的问题都一样再问:应该不是再问:第4题就两个步骤?再答:是的再问:最后一步是x-
(3-x分之x-1)平方÷(x平方-6x+9分之9-x平方)平方*x平方-2x+1分之6+2x=[(x-1)/(3-x)]²÷[(9-x²)/(x²-6x+9)]
x+3分之x+x平方-9分之6等于x-3分之1两边乘(x+3)(x-3)x(x-3)+6=x+3x²-3x+6=x+3x²-4x+3=0(x-3)(x-1)=0x1=3x2=1由于
x的平方-9分之1-x-3分之1除以x-1分之6+2x=1/(x^2-9)-1/(x-3)*(x-1)/2(3+x)=(2-(x-1))/2(x^2-9)=(3-x)/2(x^2-9)=-(x-3)/
=(x+2)(x-1)/(x-3)×(x-3)²/(x+2)=(x-1)(x-3)=x²-4x+3
x-3分之5-x方-9分之x-2+2x-6分之x-1=5/(x-3)-(x-2)/(x^2-9)+(x-1)/2(x-3)=(10(x+3)-2(x-2)+(x-1)(x+3))/2(x+3)(x-3
原式=3(X-3)/[2(X-3)(X+2)]-(X-3)/[(X-2)(X-3)]+2X/[(X+3)(X-3)]=3/[2(X+2)]-1/(X-2)+2x/[(X+3)(X-3)]=(X-10)
x平方-6x+8=x²-2×3x+9-9+8=(x-3)²-1=(x-3-1)(x-3+1)=(x-4)(x-2)x平方+x-6=(x-2)(x+3)12+x-x平方=(4-x)(
2x/3=x²/12+3/x²+4/xx²/12+3/x²=2x/3-4/xx²/4+9/x²=2x-12/x(x/2-3/x)²
(x²+6x+9)分之(x-3)+(9-x²)分之x=(x²+6x+9)分之(x-3)-(x²-9)分之x=(x+3)²分之(x-3)-[(x+3)(
x+2/(x的平方-2x)-(x-1)/(x的平方-4x+4)=x+2/(x(x-2))-(x-1)/(x-2)^2=(x^2-4-(x^2-x))/x(x-2)^2=(x-4)/x(x-2)^2
2/(x+3)(x-3)+(x-2)/x(x-3)=1/x(x+3)两边乘x(x+3)(x-3)2x+x^2+x-6=x-3x^2+2x-3=0(x+3)(x-1)=0x+3在分母,不等于0所以x=1
原式=1/(x+1)*[(x-3)/(x+3)^2+2/(x+3)]-x/(x+3)(x-3)=1/(x+1)[3(x+1)/(x+3)^2]-x/(x+3)(x-3)=3/(x+3)^2-x/(x+
=(x+2)/(x-3)×(x-3)²/(x+2)(x-2)=(x-3)/(x-2)
原式=1/(x-3)-1/2(x+3)-x/(x-3)²=[2(x+3)(x-3)-(x-3)²-2x(x+3)]/[2(x+3)(x-3)²]=(2x²-18
原式=6/x^2-9-x-1/6-x2=1/2即12+(x-1)(x+3)/2(x+3)(x-3)=1/2即(x-3)(x+4)=0∴x=3(舍)或x=-4很高兴为您解答,【学习宝典】团队为您答题.请
=(x+1)(x-1)/(x+3)²×[-1/(x-1)]×(x+3)/(x²+4)=-(x+1)/(x+3)(x²+4)
1/(x²-6x+9)+x/(9-x²)+1/(2x+6)=1/(x-3)²-x/[(x+3)(x-3)]+1/[2(x+3)]=[2(x+3)-2x(x-3)+(x-3
