去括号后合并同类项-1/2(4xy-8x^2y^2)+1/3(xy-6x^2y^2)去括号后合并同类项-1/2(4xy-8x^2y^2)+1/3(xy-6x^2y^2)最好有解题思路
去括号后合并同类项-1/2(4xy-8x^2y^2)+1/3(xy-6x^2y^2)
去括号后合并同类项
-1/2(4xy-8x^2y^2)+1/3(xy-6x^2y^2)
最好有解题思路

去括号后合并同类项-1/2(4xy-8x^2y^2)+1/3(xy-6x^2y^2)去括号后合并同类项-1/2(4xy-8x^2y^2)+1/3(xy-6x^2y^2)最好有解题思路
=-2xy+4x^2y^2+xy/3-2x^2y^2
=-5xy/5+2x^2y^2
