See the entire simplification process below:

Explanation:

First, remove all the terms from parenthesis. Be sure to handle the signs of the individual terms correctly:

7x^3 - 1 - 15x^3 - 4x^2 + x - 37x3115x34x2+x3

Next, rewrite the expression to group like terms:

7x^3 - 15x^3 - 4x^2 + x - 3 - 17x315x34x2+x31

Now, combine like terms to complete the simplification:

(7 - 15)x^3 - 4x^2 + x - 3(715)x34x2+x3

-8x^3 - 4x^2 + x - 38x34x2+x3
