Question:

add the following
(8x4 – 3x2 + 6x + 1), (5x3 – 4x2 - 2x + 2) and (-2x4 + 6x - 3)

Answer:
8x^4 – 3x^2 + 6x + 1 + 5x^3 – 4x^2 - 2x + 2 - 2x^4 + 6x -3

8x^4 – 3x^2 + 6x + 1 + 5x^3 – 4x^2 - 2x + 2 -2x^4 + 6x - 3


Collect like terms...

==> 8x^4 -2x^4 + 5x^3 – 3x^2 – 4x^2 + 6x - 2x + 6x + 1 + 2 - 3



==> 6x^4 + 5x^3 – 7x^2 + 10 x + 0


So sum is 6x^4 + 5x^3 – 7x^2 + 10 x + 0



Hope you found the explanation useful.


Warm Regards.
