问题描述：
(1)8x^3+4x^2-2x-1 (2)4a^2-20ab+25b^2-36 (3)4xy+1-4x^2-y^2 (4)a^4b+a^3b^2_a^2b^3-ab^4 (5)x^6-y^6-2x^3+1 (6)x^2(x+1)-y(xy+x)
都是分解因式的题目 要写具体过程
答
应该是因式分解吧1.8x^3+4x^2-2x-1=(8x^3+4x^2) - (2x+1)=(4x^2-1)(2x+1)=(2x-1) * (2x+1)^22.4a^2-20ab+25b^2-36=(4a^2-20ab+25b^2) - 36 =(2a-5b)^2 - 36=(2a-5b-6)(2a-5b+6)3.4xy+1-4x^2-y^2=1 - (4x^2 + 4xy - y...
