$a + (\frac{1}{2} a^{2} - 3 - 2 a - 4)$

Step 1

Remove parentheses.

$a + \frac{1}{2} a^{2} - 3 - 2 a - 4$

Step 2

Combine $\frac{1}{2}$ and $a^{2}$ .

$a + \frac{a^{2}}{2} - 3 - 2 a - 4$

Step 3

Subtract $2 a$ from $a$ .

$- a + \frac{a^{2}}{2} - 3 - 4$

Step 4

Simplify the expression.

Step 4.1

Subtract $4$ from $- 3$ .

$- a + \frac{a^{2}}{2} - 7$

Step 4.2

Reorder $- a$ and $\frac{a^{2}}{2}$ .

$\frac{a^{2}}{2} - a - 7$

$\frac{a^{2}}{2} - a - 7$
