Write the coefficient of :
8 in `a^(2) - 8ax + a`

Answer

To find the coefficient of 8 in the expression \( a^2 - 8ax + a \), we will follow these steps:

### Step 1: Identify the expression
The given expression is:
\[ a^2 - 8ax + a \]

### Step 2: Break down the expression into its terms
The expression consists of three terms:
1. \( a^2 \)
2. \( -8ax \)
3. \( a \)

### Step 3: Locate the term containing 8
We need to find the coefficient of 8. Looking at the terms, we see that the term \( -8ax \) contains the number 8.

### Step 4: Identify the coefficient of 8
In the term \( -8ax \), the coefficient of 8 is the factor that multiplies the variable \( ax \). Thus, the coefficient of 8 in this term is:
\[ -ax \]

### Conclusion
Therefore, the coefficient of 8 in the expression \( a^2 - 8ax + a \) is:
\[ \text{Coefficient of 8} = -ax \]
