Answer: The required sum is [tex]14x^2+17x.[/tex]
Step-by-step explanation: We are given to find the following sum :
[tex]S=(8x^2+17x)+6x^2.[/tex]
To find the required sum, we need to the add the coefficients of the same powers of unknown variable x.
The summation is as follows :
[tex]S\\\\=(8x^2+17x)+6x^2\\\\=8x^2+17x+6x^2\\\\=(8+6)x^2+17x\\\\=14x^2+17x.[/tex]
Thus, the required sum is [tex]14x^2+17x.[/tex]
