$f (x) = 2 x^{2} - 4 x - 3$ $g (x) = 2 x^{2} - 16$

Step 1

Replace the function designators with the actual functions in $f (x) + g (x)$ .

$2 x^{2} - 4 x - 3 + 2 x^{2} - 16$

Step 2

Simplify.

Step 2.1

Add $2 x^{2}$ and $2 x^{2}$ .

$4 x^{2} - 4 x - 3 - 16$

Step 2.2

Subtract $16$ from $- 3$ .

$4 x^{2} - 4 x - 19$
