Question 82680
{{{(x + a)((x ^ 2 - ax) / x)}}} Start with the given expression


{{{(x + a)((x ^ 2 - ax) / x)}}}

{{{(x*x^2 - x*ax + a*x ^ 2 - a*ax)/x}}} FOIL across the numerators


{{{(x^3 - ax^2 + ax ^ 2 - a^2x)/x}}} Multiply


{{{(x^3 - a^2x)/x}}} Combine like terms


{{{x(x^2- a^2)/x}}} Factor out an x


{{{cross(x)(x^2 - a^2)/cross(x)}}} Divide and cancel out the x terms


{{{x^2- a^2}}} So this is your answer


So the answer is a
