Verified Answer :

8x^2 + 17x + 6x^2....combine like terms
14x^2 + 17x

Answer:  The required sum is \(14x^2+17x.\)

Step-by-step explanation:  We are given to find the following sum :

\(S=(8x^2+17x)+6x^2.\)

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 :

\(S\\\\=(8x^2+17x)+6x^2\\\\=8x^2+17x+6x^2\\\\=(8+6)x^2+17x\\\\=14x^2+17x.\)

Thus, the required sum is \(14x^2+17x.\)
