27x3 – 1 27, x3, and 1 are all perfect cubes, so we have the difference of cubes. (3x)3 – (1)3 = (3x – 1)[(3x)2 + (3x)(1) + 12] = (3x – 1)(9x2 + 9x + 1) x6 + 8 x6 = (x2)3 8 = (2)3 so this is the sum of cubes (x2 + 2)(x4 – 2x + 4) x2 + 6x + 9 x2 and 9 are both perfect squares, and 6 is twice the square root of 9 ...
