$(a^{2} - a b) + (a^{2} + 2 a b) + (a - 2 a^{2})$

Step 1

Remove parentheses.

$a^{2} - a b + a^{2} + 2 a b + a - 2 a^{2}$

Step 2

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

$2 a^{2} - a b + 2 a b + a - 2 a^{2}$

Step 3

Combine the opposite terms in $2 a^{2} - a b + 2 a b + a - 2 a^{2}$ .

Step 3.1

Subtract $2 a^{2}$ from $2 a^{2}$ .

$- a b + 2 a b + a + 0$

Step 3.2

Add $- a b + 2 a b + a$ and $0$ .

$- a b + 2 a b + a$

Step 4

Add $- a b$ and $2 a b$ .

$1 a b + a$

Step 5

Multiply $a$ by $1$ .

$a b + a$
