I am trying to factor this binomial completely can you please help?
:
x^3 - 1000
:
You should recognize this as the "difference of cubes"
:
In the "special factoring formulas" section you will find the factoring for this:
a^3 - b^3 = (a-b)(a^2 + ab + b^2)
;
Applying this to this problem you would have:
x^3 - 1000 = (x-10)(x^2 + 10x + 100)
