(x-1)^2=4(x-3)^2(x-1)^2=4(x-3)^2(x-1)^2=4(x-3)^2(x-1)^2-[2(x-3)]^2=0(x-1+2x-6)(x-1-2x+6)=0x=5,x=7/3不

(x-1)^2=4(x-3)^2
(x-1)^2=4(x-3)^2

(x-1)^2=4(x-3)^2
(x-1)^2-[2(x-3)]^2=0
(x-1+2x-6)(x-1-2x+6)=0
x=5,x=7/3

不是吧~!直接开了 就可以解出来了啊

^2这个是平方的意思吗?
(X-1)^2=4(X-3)^2
(X-1)^2=[2(X-3)]^2
X-1=2X-6
X-2X=-5
-X=-5
X=5

(x-1)^2=4(x-3)^2
(x-1)^2-4(x-3)^2 =0
(x-1+4x-12)(x-1-4x+12)=0
(5x-13)(11-3x)=0
x1=13/5
x2=11/3
