(4x-3)²=3(4x-3)-2解方程
问题描述:
(4x-3)²=3(4x-3)-2解方程
答
(4x-3)²=3(4x-3)-2
(4x-3)²-3(4x-3)+2=0
(4X-3-2)(4X-3-1)=0
(4X-5)(4X-4)=0
4X-5=0或4X-4=0
X1=5/4,X2 =1
答
(4x-3)²=3(4x-3)-2
(4x-3)²-3(4x-3)+2=0
(4x-3-2)(4x-3-1)=0
(4x-5)(4x-4)=0
x=5/4,x=1
答
(4x-3)²-3(4x-3)+2=0
(4x-3-2)(4x-3-1)=0
(4x-5)(4x-4)=0
∴x=5/4 x=1
