First, remove the parenthesis:

5 x^{3} - 7 x + 7 x^{3} + 5 x

Second, group like terms:

5 x^{3} + 7 x^{3} - 7 x + 5 x

Combine like terms:

(5 + 7) x^{3} + (- 7 + 5) x

12 x^{3} - 2 x

Given:

(5 x^{3} - 7 x) + (7 x^{3} + 5 x)

Combine

5 x^{3} and 7 x^{3}

to get

12 x^{3}

12 x^{3} - 7 x + 5 x

Combine -7x and 5x to get -2x.
Therefore,

12 x^{3} - 2 x
