Simplify (-3x^5-x^4-x^3+2x^2)-(x^5-x^4+x^3-3x^2)

$(- 3 x^{5} - x^{4} - x^{3} + 2 x^{2}) - (x^{5} - x^{4} + x^{3} - 3 x^{2})$

Step 1

Simplify each term.

Apply the distributive property.

$- 3 x^{5} - x^{4} - x^{3} + 2 x^{2} - x^{5} - - x^{4} - x^{3} - (- 3 x^{2})$

Simplify.

Multiply $- - x^{4}$ .

Multiply $- 1$ by $- 1$ .

$- 3 x^{5} - x^{4} - x^{3} + 2 x^{2} - x^{5} + 1 x^{4} - x^{3} - (- 3 x^{2})$

Multiply $x^{4}$ by $1$ .

$- 3 x^{5} - x^{4} - x^{3} + 2 x^{2} - x^{5} + x^{4} - x^{3} - (- 3 x^{2})$

Multiply $- 3$ by $- 1$ .

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

Step 2
