**Problem (1):** \(-3x^{2} - 8x + 6\)
**Problem (2):** \(30x^{3} - 12x^{2} - 18x\)
Solución
Sure, let's solve each problem step by step and match them with their correct simplified answers.
---
### **Problem (1)**
**Subtract and simplify:**
\[ \left(-3 x^{2} - 5 x + 2\right) - (3 x - 4) \]
**Solution:**
1. **Distribute the subtraction sign:**
\[
-3x^2 - 5x + 2 - 3x + 4
\]
2. **Combine like terms:**
\[
-3x^2 + (-5x - 3x) + (2 + 4) = -3x^2 - 8x + 6
\]
**Answer:**
\[
-3x^{2} - 8x + 6
\]
---
### **Problem (2)**
**Multiply and simplify:**
\[ -6x \left( -5x^{2} + 2x + 3 \right) \]
**Solution:**
1. **Distribute \(-6x\) to each term inside the parentheses:**
\[
(-6x)(-5x^2) + (-6x)(2x) + (-6x)(3)
\]
2. **Perform the multiplication:**
\[
30x^3 - 12x^2 - 18x
\]
**Answer:**
\[
30x^{3} - 12x^{2} - 18x
\]
---
### **Summary of Matches:**
1. **Problem (1):** \(-3x^{2} - 8x + 6\)
2. **Problem (2):** \(30x^{3} - 12x^{2} - 18x\)

The Deep Dive
To solve the first problem, start by distributing the negative sign to the terms in the second parentheses: \( -3x^2 - 5x + 2 - 3x + 4 \). Combining like terms results in \( -3x^2 - 8x + 6 \), which can’t be simplified further. For the second problem, distribute \( -6x \) into the polynomial: \( -6x(-5x^2) + (-6x)(2x) + (-6x)(3) \) gives \( 30x^3 - 12x^2 - 18x \). Everything is already simplified, so that’s your final answer!
