จงแยกตัวประกอบของ 1,000 - x3
1,000 - x3 = (10 - x)(100 + 10x + x2)
1,000 - x3 = (10 + x)(100 + 10x - x2)
1,000 - x3 = (10 - x)(100 + 10x - x2)
1,000 - x3 = (10 + x)(100 - 10x + x2)

จงแยกตัวประกอบของ x3 + 1
x3 + 1 = (x + 1)(x2 + x + 1)
x3 + 1 = (x + 1)(x2 - x + 1)
x3 + 1 = (x - 1)(x2 - x + 1)
x3 + 1 = (x - 1)(x2 + x + 1)

จงแยกตัวประกอบของ x3 - 6x2 + 12x - 8
x3 - 6x2 + 12x - 8=(x + 2)2(x - 2)
x3 - 6x2 + 12x - 8=(x - 2)2(x + 2)
x3 - 6x2 + 12x - 8 = (x + 2)3
x3 - 6x2 + 12x - 8 = (x - 2)3
