What is the product of -2x%5E3+%2B+x+-+5 and x%5E3+-+3x+-+4 ?
(a) show your work

(b) is the product of -2x%5E3+%2B+x+-+5 and x%5E3+-+3x+-+4+ equal to the product of
x%5E3+-+3x+-+4 and+-2x%5E3+%2B+x+-+5 ?
yes, because it’s commutation: a%2Ab=b%2Aa
check:
-> same as in (a)

What is the product of -2x^3 + x - 5 and x^3 - 3x - 4 ?
---------------------------------------------------------

               x^3      -3x      -4
------------------------------------------------

-2x^3 |      -2x^6      6x^4     8x^3
      |
x     |       x^4       -3x^2     -4x
      |
-5    |      -5x^3      15x       20
--------------------------------------------------


Their sum:
-2x%5E6%2B7x%5E4%2B3x%5E3-3x%5E2%2B11x%2B20
