初二的题,拜托啊(2x^2-5x^2+3x-2)除以(-x+1+2x^2)=_____填空
初二的题,拜托啊(2x^2-5x^2+3x-2)除以(-x+1+2x^2)=_____
2x^3-5x^2+3x-2
=x(-x+1+2x^2)-4x^2+2x-2
=x(-x+1+2x^2)-2(-x+1+2x^2)
=(x-2)(-x+1+2x^2)
(2x^2-5x^2+3x-2)除以(-x+1+2x^2)=x-2.

(2x^3-5x^2+3x-2)/(-x+1+2x^2)
=[(2x^2-x^2+x)-(4x^2-2x+2)]/(-x+1+2x^2)
=(2x^2-x+1)(x-2)/(2x^2-x+1)
=x-2
