# Find the correct sum of the polynomials (3x^{3} − 5x − 8) + (5x^{3 }+ 7x + 3)

The algebraic expressions having variables and coefficients are called polynomials.

## Answer: The sum of the polynomials (3x^{3} − 5x − 8) and (5x^{3 }+ 7x + 3) is 8x^{3} + 2x − 5.

Let's add the polynomials.

**Explanation:**

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

### Thus, the sum of the polynomials (3x^{3} − 5x − 8) and (5x^{3 }+ 7x + 3) is 8x^{3} + 2x − 5.
