Question 54205
I left this one alone because I wasn't sure whether you meant:
{{{(x+a)(x^2-ax/x)}}} or {{{(x+a)((x^2-ax)/x)}}}
Nobody else has taken this one on, so I'm going to show you what to do in either case:
If you meant:
{{{(x+a)(x^2-ax/x)}}}
{{{(x+a)(x^2-a*cross(x)/cross(x))}}}
{{{(x+a)(x^2-a)}}}
{{{x(x^2)+x(-a)+a(x^2)+a(-a)}}}
{{{x^3-ax+ax^2-a^2}}}
{{{highlight(x^3+ax^2-ax-a^2)}}}
:
If you meant:
{{{(x+a)((x^2-ax)/x)}}}
{{{(x+a)(x^2/x-ax/x)}}}
{{{(x+a)(x*x/x-ax/x)}}}
{{{(x+a)(cross(x)*x/cross(x)-a*cross(x)/cross(x))}}}
{{{(x+a)(x-a)}}}
{{{x(x)+x(-a)+a(x)+a(-a)}}}
{{{x^2-ax+ax-a^2}}}
{{{highlight(x^2-a^2)}}}
Happy Calculating!!!
