$f (x) = 2 (3 a^{2}) - (3 a) + 4$

Step 1

Rewrite the function as an equation.

$y = 2 (3 a^{2}) - (3 a) + 4$

Step 2

Remove parentheses.

$y = 2 \cdot (3 a^{2}) - (3 a) + 4$

Step 3

Remove parentheses.

$y = 2 \cdot (3 a^{2}) - 1 \cdot (3 a) + 4$

Step 4

Step 4.1

Multiply $3$ by $2$ .

$y = 6 a^{2} - 1 \cdot (3 a) + 4$

Step 4.2

Multiply $3$ by $- 1$ .

$y = 6 a^{2} - 3 a + 4$

$y = 6 a^{2} - 3 a + 4$
