$2 x^{3} - 4 x^{2} + 6 x - 3 x^{3} + 6 x^{2} - 8 x + 12 - 3 x^{3} + 2 x^{2} - 4 x - 7$

Step 1

Subtract $3 x^{3}$ from $2 x^{3}$ .

$- x^{3} - 4 x^{2} + 6 x + 6 x^{2} - 8 x + 12 - 3 x^{3} + 2 x^{2} - 4 x - 7$

Step 2

Subtract $3 x^{3}$ from $- x^{3}$ .

$- 4 x^{3} - 4 x^{2} + 6 x + 6 x^{2} - 8 x + 12 + 2 x^{2} - 4 x - 7$

Step 3

Add $- 4 x^{2}$ and $6 x^{2}$ .

$- 4 x^{3} + 2 x^{2} + 6 x - 8 x + 12 + 2 x^{2} - 4 x - 7$

Step 4

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

$- 4 x^{3} + 4 x^{2} + 6 x - 8 x + 12 - 4 x - 7$

Step 5

Subtract $8 x$ from $6 x$ .

$- 4 x^{3} + 4 x^{2} - 2 x + 12 - 4 x - 7$

Step 6

Subtract $4 x$ from $- 2 x$ .

$- 4 x^{3} + 4 x^{2} - 6 x + 12 - 7$

Step 7

Subtract $7$ from $12$ .

$- 4 x^{3} + 4 x^{2} - 6 x + 5$
