解方程3|x|-5=|x|-2/2+1

解方程3|x|-5=|x|-2/2+1

3(x一2)=2一5(x一2)这个方程怎么解

3(x-2)=2-5(x-2)

3x-6=2-5x+10

8x=18

x=9/4

解这个方程:3(x-5)²=2(5-x)

3(x-5)²=2(5-x)

3(x-5)²+2(X-5)=0

(x-5)(3x-15+2)=0

(x-5)(3x-13)=0

x1=5,x2=13/3

3(x-5)²=2(5-x) {用因式分解法解方程}

3(x-5)²=2(5-x)

3(x-5)²-2(5-x)=0

3(x-5)²+2(x-5)=0

(x-5)[3(x-5)+2]=0

(x-5)(3x-13)=0

所以x-5=0或3x-13=0

所以x=5或x=13/3

3(X-5)^2=2(5-X)这个二元一次 要步骤和解法

3(X-5)^2 =2(5-X)

3(X-5)^2= -2(X-5)

3(X-5)^2+2(X-5)=0

(X-5)[3(X-5)+2]=0

(X-5)(3X-15+2)=0

(X-5)(3X-13)=0

X=5 or X=(13/3)
