分解因式:-x^3+x^2-1/4x分解因式:-x^3+x^2-1/4x分解因式:-x^3+x^2-1/4x-x"''+x"-1/4x=-(1/4x)(4x"-4x+1)=-(1/4x)(2x-1)"或

分解因式:-x^3+ x^2-1/4x
分解因式:-x^3+ x^2-1/4x

分解因式:-x^3+ x^2-1/4x
- x"' + x" - 1/4x
= - (1/4x)( 4x" - 4x + 1 )
= - (1/4x)( 2x - 1 )"
或者
= - x( x" - x + 1/4 )
= - x[ x" - (2/2)x + (1/2)" ]
= - x( x - 1/2 )"
