(1)3x(x-2)+2(x-2)=0 (2)解方程:(x-根号2)=5x(根号2-x)

(1)3x(x-2)+2(x-2)=0 (2)解方程:(x-根号2)=5x(根号2-x)
(1)3x(x-2)+2(x-2)=0 (2)解方程:(x-根号2)=5x(根号2-x)

(1)3x(x-2)+2(x-2)=0 (2)解方程:(x-根号2)=5x(根号2-x)
(1)3x(x-2)+2(x-2)=0
(x-2)(3x+2)=0
x=2或x=-2/3
(2)解方程:(x-根号2)=5x(根号2-x)
(x-根号2)-5x(根号2-x)=0
(x-根号2)+5x(x-根号2)=0
(x-根号2)(1+5x)=0
x=根号2 或x=-1/5
