The problem is to divide \( (x^7 + x^5 - 10x^3 + 12) \) by \( (x + 2) \). We will use polynomial division to solve this. Here’s the step-by-step process:

### Step 1: Set Up the Division
The dividend is \( x^7 + x^5 - 10x^3 + 12 \), and the divisor is \( x + 2 \). 

### Step 2: Divide the Leading Terms
1. Divide the leading term of the dividend (\( x^7 \)) by the leading term of the divisor (\( x \)). This gives:
   \[
   x^7 \div x = x^6
   \]
   
2. Multiply \( x^6 \) by \( (x + 2) \):
   \[
   x^6 \cdot (x + 2) = x^7 + 2x^6
   \]
   
3. Subtract this result from the original polynomial:
   \[
   (x^7 + x^5 - 10x^3 + 12) - (x^7 + 2x^6) = -2x^6 + x^5 - 10x^3 + 12
   \]

### Step 3: Repeat the Process
4. Divide the new leading term (\( -2x^6 \)) by \( x \):
   \[
   -2x^6 \div x = -2x^5
   \]
   
5. Multiply \( -2x^5 \) by \( (x + 2) \):
   \[
   -2x^5 \cdot (x + 2) = -2x^6 - 4x^5
   \]
   
6. Subtract:
   \[
   (-2x^6 + x^5 - 10x^3 + 12) - (-2x^6 - 4x^5) = 5x^5 - 10x^3 + 12
   \]

### Step 4: Continue the Division
7. Divide \( 5x^5 \) by \( x \):
   \[
   5x^5 \div x = 5x^4
   \]
   
8. Multiply \( 5x^4 \) by \( (x + 2) \):
   \[
   5x^4 \cdot (x + 2) = 5x^5 + 10x^4
   \]
   
9. Subtract:
   \[
   (5x^5 - 10x^3 + 12) - (5x^5 + 10x^4) = -10x^4 - 10x^3 + 12
   \]

### Step 5: Repeat Until the End
Continue this process until the degree of the remainder is less than the degree of the divisor.
