Question

用配方法解下列方程：x^2-2√3x+3=0 1/3x^2-1/2x+3/16=0 x^2+（√2+1）x+√2=0 （x+2）（x-2）= 2√2x

要快啊。10月7日之前给我答案
x^2-2√3x+3=0
1/3x^2-1/2x+3/16=0
x^2+（√2+1）x+√2=0
x+2）（x-2）= 2√2x

Answer 1

1. (x-√3)^2=0 x=√3

2. x^2-3/2x+9/16=0 得(x-3/4)^2=0 x=3/4

3. [x+(√2+1)/2]^2=[（√2-1)/2]^2
得x=-1或x=-√2

4. x^2- 2√2x-4=0
(x-√2)^2=6=(√6)^2
得x=√2±√6
