解方程:2x-1/x-4x/2x²-1=3
人气:292 ℃ 时间:2020-01-29 06:51:50
解答
原方程为2x-1/x-4x/2x²-4=0
原方程两边同时乘以2x²
得2x(2x-1)-4x-8x²=0
即4x²-2x-4x-8x²=0
-4x²-6x=0
-2x(2x+3)=0
由原方程x为除数不能为0,所以2x+3=0 x=-3/2
推荐
(2x+1)(4x²-2x+1)-2x(4x²+1)=0,解方程,
x²+4x+9=2x-11
解方程 (1)x²-2x-3=0 (2)x²+4x+2=0 (3)x²-2x-2=0
解方程2x²-4x+15=0 (求过程)~
解方程:x²-1分之x²-4x+1=x+1分之2x
证明f(x)=[√(1 x²) x-1]
