UpStudy AI · Accepted Answer

To add the given polynomials using vertical form, follow these steps:

$$
\begin{array}{r}
\phantom{+}4x^{3} - 9x^{2} + \phantom{0}8 \
+ \; 8x^{3} + 5x^{2} + 19 \
\hline
\end{array}
$$

**Step-by-Step Addition:**

1. **Add the $$x^{3}$$ terms:**
   $$
   4x^{3} + 8x^{3} = 12x^{3}
   $$

2. **Add the $$x^{2}$$ terms:**
   $$
   -9x^{2} + 5x^{2} = -4x^{2}
   $$

3. **Add the constant terms:**
   $$
   8 + 19 = 27
   $$

**Combine all the results:**
$$
12x^{3} - 4x^{2} + 27
$$

**Final Answer:**
$$
12x^{3} - 4x^{2} + 27
$$
$$12x^{3} - 4x^{2} + 27$$
