整式的乘除运算(x^2-1/9)(x^2+1/3x+1/9)(x^2-1/3x+1/9)

整式的乘除运算(x^2-1/9)(x^2+1/3x+1/9)(x^2-1/3x+1/9)
整式的乘除运算
(x^2-1/9)(x^2+1/3x+1/9)(x^2-1/3x+1/9)

整式的乘除运算(x^2-1/9)(x^2+1/3x+1/9)(x^2-1/3x+1/9)
(x^2-1/9)(x^2+1/3x+1/9)(x^2-1/3x+1/9)
=(x-1/3)(1+1/3)(x^2+1/3x+1/9)(x^2-1/3x+1/9)
=(x-1/3)(x^2+1/3x+1/9)(1+1/3)(x^2-1/3x+1/9)
=(x^3-1/3^3)(x^3+1/3^3)
=x^6-1/3^6
