Question

Add.

Your answer should be an expanded polynomial in
standard form.
(-5n4 + 8) + (5n4 + 8n³ + 3n²);
=

Answer 1

8n³ + 3n² + 8

Explanation:

To find the sum of the two polynomials, we can simply add the corresponding terms:

(-5n^4 + 8) + (5n^4 + 8n³ + 3n²)

Combine the like terms:

(-5n^4 + 5n^4) + 8n³ + 3n² + 8

The -5n^4 and 5n^4 terms cancel each other out:

0 + 8n³ + 3n² + 8

So the expanded polynomial in standard form is:

8n³ + 3n² + 8
