解几个方程,3x²+2x=2x²+4根号2x+3=05x(x-3)=(x-3)(x+1)(x-4)²-(5-2x)²=0
解几个方程,
3x²+2x=2
x²+4根号2x+3=0
5x(x-3)=(x-3)(x+1)
(x-4)²-(5-2x)²=0
解几个方程,3x²+2x=2x²+4根号2x+3=05x(x-3)=(x-3)(x+1)(x-4)²-(5-2x)²=0
3x^2+2x-2=0
x=(±√7-1)/3
x^2+4x√2+3=0
x=±√5-2√2
5x(x-3)=(x-3)(x+1)
x=3 和 x=1/4
(x-4)^2-(5-2x)^2=0
x=1 和 x=3
(1)x=(-1-根号7)/3 或 (-1+根号7)/3
(2)没看清题
(3)x=3或x=1/4
(4)x=1 ,x=-9
1.(-1±根号7)/3
2.无解
3.1/4,-3
4.1,3
x1=-1+根号7/3 x2=-1-根号7/3
x=-6/5
x1=-3/2 x2=-2
x1=3 x2=1
