1/2x(-3x^2+4x+3)-1/3x^2(2x-6x^2),求结果

问题描述:

1/2x(-3x^2+4x+3)-1/3x^2(2x-6x^2),求结果

1/2x(-3x^2+4x+3)-1/3x^2(2x-6x^2)
=-3/2x³+2x²+3/2x-2/3x³+2x⁴
=2x⁴+2x²+3/2x不对吧,正确的是不是这样:1/2x(-3x^2+4x+3)-1/3x^2(2x-6x^2)=-3/2x³+2x²+3/2x-2/3x³+2x⁴ =2x⁴+2x²+3/2x-13/6x^31/2x(-3x^2+4x+3)-1/3x^2(2x-6x^2)=-3/2x³+2x²+3/2x-2/3x³+2x⁴=2x⁴-13/6x³+2x²+3/2x (是的,开始看错了)
