Question 135417
Expand:
{{{(x-5)^3}}} Rewrite this as:
{{{(x-5)(x-5)(x-5)}}} Now multiply the first two factors using the FOIL method.
{{{(x-5)(x-5) = x^2-5x-5x+25}}} = {{{x^2-10x+25}}} now multiply this by the third factor.
{{{(x-5)(x^2-10x+25) = x^3-10x^2+25x-5x^2+50x-125}}} Simplify to get:
{{{x^3-15x^2+75x-125}}}
