Simplify (x^5+x^3+3x-2)+(x^4+9x^2-8)

$(x^{5} + x^{3} + 3 x - 2) + (x^{4} + 9 x^{2} - 8)$

Step 1

Remove parentheses.

$x^{5} + x^{3} + 3 x - 2 + x^{4} + 9 x^{2} - 8$

Step 2

Subtract $8$ from $- 2$ .

$x^{5} + x^{3} + 3 x + x^{4} + 9 x^{2} - 10$

Step 3

Move $3 x$ .

$x^{5} + x^{3} + x^{4} + 9 x^{2} + 3 x - 10$

Step 4

Move $x^{3}$ .

$x^{5} + x^{4} + x^{3} + 9 x^{2} + 3 x - 10$
