Simplify -3x+x^3-2x^2-4x^3-2x^2-4x

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

Step 1

Subtract $4 x$ from $- 3 x$ .

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

Step 2

Subtract $4 x^{3}$ from $x^{3}$ .

$- 3 x^{3} - 2 x^{2} - 2 x^{2} - 7 x$

Step 3

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

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