$f (x) [\begin{array}{c} 3 x - x^{2} \\ 3 - x \\ 0 \end{array}]$

Step 1

Multiply $f (x)$ by each element of the matrix.

$[\begin{array}{c} f (x) (3 x - x^{2}) \\ f (x) (3 - x) \\ f (x) \cdot 0 \end{array}]$

Step 2

Simplify each element in the matrix.

Apply the distributive property.

$[\begin{array}{c} f (x) (3 x) + f (x) (- x^{2}) \\ f (x) (3 - x) \\ f (x) \cdot 0 \end{array}]$

Rewrite using the commutative property of multiplication.

$[\begin{array}{c} 3 f (x) x + f (x) (- x^{2}) \\ f (x) (3 - x) \\ f (x) \cdot 0 \end{array}]$

Rewrite using the commutative property of multiplication.

$[\begin{array}{c} 3 f (x) x - f (x) x^{2} \\ f (x) (3 - x) \\ f (x) \cdot 0 \end{array}]$

Reorder factors in $3 f (x) x - f (x) x^{2}$ .

$[\begin{array}{c} 3 x f (x) - x^{2} f (x) \\ f (x) (3 - x) \\ f (x) \cdot 0 \end{array}]$

Apply the distributive property.

$[\begin{array}{c} 3 x f (x) - x^{2} f (x) \\ f (x) \cdot 3 + f (x) (- x) \\ f (x) \cdot 0 \end{array}]$

Move $3$ to the left of $f (x)$ .

$[\begin{array}{c} 3 x f (x) - x^{2} f (x) \\ 3 \cdot f (x) + f (x) (- x) \\ f (x) \cdot 0 \end{array}]$

Rewrite using the commutative property of multiplication.

$[\begin{array}{c} 3 x f (x) - x^{2} f (x) \\ 3 \cdot f (x) - f (x) x \\ f (x) \cdot 0 \end{array}]$

Reorder factors in $3 f (x) - f (x) x$ .

$[\begin{array}{c} 3 x f (x) - x^{2} f (x) \\ 3 f (x) - x f (x) \\ f (x) \cdot 0 \end{array}]$

Multiply $f (x)$ by $0$ .

$[\begin{array}{c} 3 x f (x) - x^{2} f (x) \\ 3 f (x) - x f (x) \\ 0 \end{array}]$
