To find the additional linear factors of the polynomial \( x^3 - 6x^2 + 11x - 6 \), given that \( x - 3 \) is a factor, we can use polynomial division or synthetic division to divide the polynomial by \( x - 3 \).
-
Synthetic Division: We perform synthetic division of \( x^3 - 6x^2 + 11x - 6 \) by \( x - 3 \).
3 | 1 -6 11 -6 | 3 -9 6 ------------------- 1 -3 2 0
The result is \( x^2 - 3x + 2 \), with a remainder of 0, confirming that \( x - 3 \) is indeed a factor.
-
Factoring the Result: Now, we need to factor \( x^2 - 3x + 2 \).
The quadratic \( x^2 - 3x + 2 \) can be factored by finding two numbers that multiply to \( 2 \) (the constant term) and add to \( -3 \) (the coefficient of \( x \)). Those numbers are \( -1 \) and \( -2 \).
Thus, we can factor:
\[ x^2 - 3x + 2 = (x - 1)(x - 2) \]
-
Combining the Factors: Therefore, the full factorization of \( x^3 - 6x^2 + 11x - 6 \) is:
\[ (x - 3)(x - 1)(x - 2) \]
From the responses given, the additional linear factors (aside from \( x - 3 \)) are:
\[ (x - 2)(x - 1) \]
Thus, the correct answer is:
\[ (x - 2)(x - 1) \]
