Solution
Solution Steps
To simplify the given expression, we need to find a common denominator. First, factor the quadratic expression in the denominator of the first fraction. Then, rewrite both fractions with the common denominator and combine them.
Solution Approach
Factor the quadratic expression \(x^2 - 6x + 5\).
Rewrite the fractions with a common denominator.
Combine the fractions and simplify.
Step 1: Factor the Quadratic Expression
We start with the expression \( x^2 - 6x + 5 \). Factoring this gives us:
\[
x^2 - 6x + 5 = (x - 5)(x - 1)
\]
Step 2: Rewrite the Fractions
The original expression is:
\[
\frac{4}{x^2 - 6x + 5} + \frac{1}{x - 5}
\]
Substituting the factored form, we have:
\[
\frac{4}{(x - 5)(x - 1)} + \frac{1}{x - 5}
\]
Step 3: Find a Common Denominator and Combine
The common denominator for the two fractions is \((x - 5)(x - 1)\). Rewriting the second fraction:
\[
\frac{1}{x - 5} = \frac{(x - 1)}{(x - 5)(x - 1)}
\]
Now, we can combine the fractions:
\[
\frac{4}{(x - 5)(x - 1)} + \frac{x - 1}{(x - 5)(x - 1)} = \frac{4 + (x - 1)}{(x - 5)(x - 1)} = \frac{x + 3}{(x - 5)(x - 1)}
\]
Final Answer
The simplified expression is:
\[
\boxed{\frac{x + 3}{(x - 5)(x - 1)}}
\]
