Rewrite 1 1 as 13 1 3. 13 − x3 1 3 - x 3. Since both terms are perfect cubes, factor using the difference of cubes formula, a3 −b3 = (a−b)(a2 + ab+b2) a 3 - b 3 = (a - b) (a 2 + a b + b 2) where a = 1 a = 1 and b = x b = x. (1−x)(12 +1x+x2) (1 - x) (1 2 + 1 x + x 2) Simplify. Tap for more steps... (1−x)(1+ x+x2) (1 - x) (1 + x + x 2)
