tresset_1 [31]
ANSWER
13 {x}^{3}  - 2 {x}^{2}  + 3x + 13

EXPLANATION

The first polynomial is
5 {x}^{3}  + 3 {x}^{2}  - 5x + 4


The second polynomial is
8 {x}^{3}  - 5 {x}^{2}  + 8x + 9


If we add the two polynomials we obtain,



(5 {x}^{3}  + 3 {x}^{2}  - 5x + 4) + (8 {x}^{3}  - 5 {x}^{2}  + 8x + 9)


Next we group like terms to obtain,


5 {x}^{3} + 8 {x}^{3}+ 3 {x}^{2}  -5 {x}^{2}   - 5x  + 8x + 9 + 4



We simplify the to obtain,


13{x}^{3} -2{x}^{2}    + 3x + 13

This is the sum of the two polynomials in descending powers of
x


Descending means from the highest power to the least.
