x^3 + 0x^2 + 0x - a^3

answered May 20, 2014 by johnperkins Top Rated User (103,080 points)
don't we have to do anything on a^3?
Do you mean where does the a^3 go?

In the bottom right of the handwritten stuff it does

-a^3 - -a^3

Same as

-a^3 + a^3 = 0

so the a^3 gets canceled out and disappears.

If you expanded (x - a)(x^2 + ax + a^2), the -a and +a^2 times'd together would make -a^3.  That's where the -a^3 went.

x-a)x^3 -a^3(x^2+ax+a^2

    -x^3 +a^3
