Explain the step by step of this factoring polynomials.
$8 x^{3} + 1$
This problem is the sum of 2 perfect cubes.
$8 x^{3} + 1 = {(2 x)}^{3} + {(1)}^{3}$
and so we know that it is the fourth special form from above. Here is the factor for this polynomials.
$8 x^{3} + 1 = (2 x + 1) (4 x^{2} - 2 x + 1)$
