(x^2-2xy+4y^2)(x+2y)-8x(x+y)(x-y) (64a^3-27b^3)\(4a-3b)-(4a+3b)^2 (x^4-x+1)/(x^2+2x-3)(x^2-2xy+4y^2)(x+2y)-8x(x+y)(x-y)(64a^3-27b^3)\(4a-3b)-(4a+3b)^2(x^4-x+1)/(x^2+2x-3)
问题描述:
(x^2-2xy+4y^2)(x+2y)-8x(x+y)(x-y) (64a^3-27b^3)\(4a-3b)-(4a+3b)^2 (x^4-x+1)/(x^2+2x-3)
(x^2-2xy+4y^2)(x+2y)-8x(x+y)(x-y)
(64a^3-27b^3)\(4a-3b)-(4a+3b)^2
(x^4-x+1)/(x^2+2x-3)
