Question 86646
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.
