To find a factor of the polynomial \( x^3 - 5x^2 + 6x \), we can start by factoring it.
First, we can factor out the common term \( x \):
\[ x^3 - 5x^2 + 6x = x(x^2 - 5x + 6) \]
Next, we need to factor the quadratic \( x^2 - 5x + 6 \). We are looking for two numbers that multiply to \( 6 \) and add up to \( -5 \). The numbers \( -2 \) and \( -3 \) fit this requirement.
Thus, we can factor the quadratic:
\[ x^2 - 5x + 6 = (x - 2)(x - 3) \]
Putting it all together, we have:
\[ x^3 - 5x^2 + 6x = x(x - 2)(x - 3) \]
From this factorization, we see the linear factors are \( x \), \( x - 2 \), and \( x - 3 \).
If \( x \) itself is one of the factors, then another correct factor from the options provided is \( x - 2 \).
Thus, the correct answer is \( x - 2 \).
