解方程3(x-5)方=2(5-x)解方程3(x-5)方=2(5-x)解方程3(x-5)方=2(5-x)3(x-5)方=2(5-x)(x-5)(3x-15+2)=0x-5=03x-15+2=0x1=5x

解方程 3(x-5)方=2(5-x)
解方程 3(x-5)方=2(5-x)

解方程 3(x-5)方=2(5-x)
3(x-5)方=2(5-x)
(x-5)(3x-15+2)=0
x-5=0 3x-15+2=0
x1=5 x2=13/3

3(x-5)²+2(x-5)=0
(x-5)(3x-15+2)=0
(x-5)(3x-13)=0
x=5,x=13/5

3(x-5)^2=2(5-x)
3(x-5)^2= -2(x-5)
3(x-5)^2+2(x-5)=0
(x-5)(3x-15+2)=0
(x-5)(3x-13)=0
(x-5)=0
x=5
(3x-13)=0
x=13/3=4又1/3

3(x-5)^2=2(5-x)
(1)x=5
(2) 当x≠5
3(5-x)=2
x=5-2/3
=13/3

3(x-5)方=2(5-x)
3(x-5)方-2(5-x)=0
3(x-5)方+2(5-x)=0
(x-5)【3(x-5)+2】=0
(x-5)(3x-13)=0
x=5
x=3分之13
