$(2 x^{2} - 1 + 3 x^{3}) + (5 - 13 x - 11 x^{2})$

Step 1

Remove parentheses.

$2 x^{2} - 1 + 3 x^{3} + 5 - 13 x - 11 x^{2}$

Step 2

Subtract $11 x^{2}$ from $2 x^{2}$ .

$- 9 x^{2} - 1 + 3 x^{3} + 5 - 13 x$

Step 3.1

Add $- 1$ and $5$ .

$- 9 x^{2} + 3 x^{3} + 4 - 13 x$

Step 3.2

Move $4$ .

$- 9 x^{2} + 3 x^{3} - 13 x + 4$

Step 3.3

Reorder $- 9 x^{2}$ and $3 x^{3}$ .

$3 x^{3} - 9 x^{2} - 13 x + 4$

$3 x^{3} - 9 x^{2} - 13 x + 4$
