x∧2(x∧2-9)½分之1的积分

x+2分之1+x分之1=x的平方+2x分之321/(x+2)+1/x=32/(x²+2x)去分母x+x+2=32x=15检验：左边=1/17+1/15=32/255右边=32/(225+30

1/x+2/(x-1)=2/(x^2-x)1/x+2/(x-1)-2/(x^2-x)=0(x-1)/x(x-1)+2x/x(x-1)-2/x(x-1)=0[(x-1)+2x-2]/x(x-1)=0(3

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)/

)【(x²-2x+1)/(x²-1)】÷【(x-1)/(x²+x)】=【(x-1）²/(x+1)（x-1)】÷【(x-1)/x(x+1)】=【(x-1）/(x+

=2x/x²-(2x-1)/x²=(2x-2x+1)/x²=1/x²

=2(x-3)/(x+3)(x-3)+(x+1)²/(x+3)(x-2)×(x-2)/(x+1)=2/(x+3)+(x+1)/(x+3)=(x+3)/(x+3)=1

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

x的平方-2x+1分之x-3÷x-1分之x的平方-9=[(x-3)/(x-1)²]*[(x-1)/(x+3)*(x-3)]=1/(x-1)(x+3)

两边乘(x+3)(x-3)3(x+3)-(x-3)=183x+9-x+3=182x=6x=3经检验,x=3则分母x-3=0是增根,舍去所以方程无解

9x的2次方分之2+6x分之1-3x分之1=2/(9x²)+1/(6x)-1/(3x)括号加得对吗?=4/(18x²)+3x/(18x²)-6x/(18x²)=

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

=x/(x+2)(x-2)-(x-2)/(x+2)(x-2)=[x-(x-2)]/(x+2)(x-2)=2/(x²-4)

(x+3)分之1-(x-3)分之1=(x²-9)分之2x两边同时乘以(x+3)(x-3)得(x-3)-(x+3)=2x-6=2xx=-6÷2x=-3很高兴为您解答,【学习宝典】团队为您答题.

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+

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

x/(x²+2x+1),(x-1)/(x²+x),1/(x²-1)式1：x/(x+1)²,式2：(x-1)/[x(x+1)],式3：1/[(x+1)(x-1)]

x＝4084y＝1＆＃47；9所以√x＝2√y＝1＆＃47；3原式＝4＊（1＆＃47；2）－2＆＃47；3－9＊y√y＝2－2＆＃47；3－1＆＃47；3＝1

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
