计算(24x^4y^2+12x^3y^3-8x^2y^4)/6x^2y^2
分别展开,x和y的幂次方相消就可以了
(24x^4y^2)/(6x^2y^2)+(12x^3y^3)/(6x^2y^2)-(8x^2y^4)/(6x^2y^2)
=4x^2y^0+2x^1y^1-4/3x^0y^2
=4x^2+2xy-4/3y^2
=2(2x^2+xy-2/3y^2)
(24x^4y^2)/(6x^2y^2)+(12x^3y^3)/(6x^2y^2)-(8x^2y^4)/(6x^2y^2)
=4x^2y^0+2x^1y^1-4/3x^0y^2
=4x^2+2xy-4/3y^2
=2(2x^2+xy-2/3y^2)
计算(x^8-x^7y+x^5y^3-x^4y^4+x^3y^5-x^y^7+y^8)(x^2+xy+y^2)
