# Find the correct sum of the polynomials (4x^{3} − 2x − 9) + (2x^{3} + 5x + 3)

Algebraic expressions that have variables and coefficients are called polynomials.

## Answer: The sum of the polynomials (4x^{3} − 2x − 9) and (2x^{3} + 5x + 3) is 6x^{3} + 3x − 6.

Let's add the given polynomials.

**Explanation:**

We add polynomials by adding the coefficients of the same power.

### Thus, the sum of polynomials (4x^{3} − 2x − 9) and (2x^{3} + 5x + 3) is 6x^{3} + 3x − 6.
