(2x-1)²=3-6x求解方程
3个回答
展开全部
( 2x - 1 )” = 3 - 6x,
( 2x - 1 )” + 6x - 3 = 0,
( 2x - 1 )” + 3( 2x - 1 ) = 0,
( 2x - 1 )( 2x - 1 + 3 ) = 0,
( 2x - 1 )( 2x + 2 ) = 0,
2( x + 1 )( 2x - 1 ) = 0,
( x + 1 )( 2x - 1 ) = 0,
解方程得,
x1 = -1,
x2 = 1/2,
( 2x - 1 )” + 6x - 3 = 0,
( 2x - 1 )” + 3( 2x - 1 ) = 0,
( 2x - 1 )( 2x - 1 + 3 ) = 0,
( 2x - 1 )( 2x + 2 ) = 0,
2( x + 1 )( 2x - 1 ) = 0,
( x + 1 )( 2x - 1 ) = 0,
解方程得,
x1 = -1,
x2 = 1/2,

(2x-1)²=3-6x
(2x-1)^2+6x-3=0
(2x-1)^2+3(2x-1)=0
(2x-1)[(2x-1)+3]=0
(2x-1)(2x+2)=0
x1=0.5, x2=-1
(2x-1)^2+6x-3=0
(2x-1)^2+3(2x-1)=0
(2x-1)[(2x-1)+3]=0
(2x-1)(2x+2)=0
