Answer :
Sure! Let's find the polynomial that represents the sum of the given expressions step-by-step:
To find the sum of the two polynomials, we need to add the coefficients of like terms together. The polynomials given are:
1. [tex]\(2x^7 + 5x + 4\)[/tex]
2. [tex]\(5x^8 + 8x\)[/tex]
Step 1: Align the polynomials by their degree terms.
[tex]\[
\begin{array}{r}
2x^7 + 0x^6 + 0x^5 + 0x^4 + 0x^3 + 0x^2 + 5x + 4 \\
+ \quad 5x^8 + 0x^7 + 0x^6 + 0x^5 + 0x^4 + 0x^3 + 8x \\
\hline
\end{array}
\][/tex]
Step 2: Add the coefficients of like terms.
- For [tex]\(x^8\)[/tex], we have no term in the first polynomial, so the result is [tex]\(5x^8\)[/tex].
- For [tex]\(x^7\)[/tex], we have [tex]\(2x^7\)[/tex].
- For [tex]\(x^6\)[/tex], [tex]\(x^5\)[/tex], [tex]\(x^4\)[/tex], [tex]\(x^3\)[/tex], and [tex]\(x^2\)[/tex], there are no terms in both polynomials, so they remain [tex]\(0\)[/tex].
- For [tex]\(x\)[/tex], add [tex]\(5x\)[/tex] from the first polynomial and [tex]\(8x\)[/tex] from the second polynomial to get [tex]\(13x\)[/tex].
- For the constant term: [tex]\(4\)[/tex] from the first polynomial since there is no constant in the second one.
Putting it together, the sum is:
[tex]\[
5x^8 + 2x^7 + 13x + 4
\][/tex]
Therefore, the polynomial representing the sum is [tex]\(5x^8 + 2x^7 + 13x + 4\)[/tex].
Unfortunately, this specific polynomial doesn't exactly match with any given options, but we should verify with the closest matching option from the list, if applicable.
Note: If provided choices differ, you should check for errors in those options accordingly.
