Webb15 mars 2016 · Use the difference of cubes identity to find: x^3-27 = (x-3)(x^2+3x+9) Both x^3 and 27=3^3 are perfect cubes. So we can use the difference of cubes identity: a^3-b^3 = (a-b)(a^2+ab+b^2) with a=x and b=3 as follows: x^3-27 =x^3-3^3 =(x-3)(x^2+x(3) + 3^2) =(x-3)(x^2+3x+9) This is as far as you can go with Real coefficients.
