3x4−4x3−2x−6

Answer 1

To add the polynomial expressions, we combine like terms from both expressions.

Let's rewrite the expressions:

**Expression #1:**
\(3x^4 - 2 - 2x^3 + 4x\)

**Expression #2:**
\(2x^3 - 6x - 4\)

Now, we will add them together:

\[
(3x^4 - 2 - 2x^3 + 4x) + (2x^3 - 6x - 4)
\]

Now combine like terms:

- The \(x^4\) term: \(3x^4\)
- The \(x^3\) terms: \(-2x^3 + 2x^3 = 0\)
- The \(x\) terms: \(4x - 6x = -2x\)
- The constant terms: \(-2 - 4 = -6\)

Putting it all together, we have:

\[
3x^4 - 2x - 6
\]

So the answer is:

**3x⁴ - 2x - 6**
