Find the correct sum of the polynomials (3x³ − 5x − 8) + (5x³ + 7x + 3)

The algebraic expressions having variables and coefficients are called polynomials.

Answer: The sum of the polynomials (3x³ − 5x − 8) and (5x³ + 7x + 3) is 8x³ + 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 (3x³ − 5x − 8) and (5x³ + 7x + 3) is 8x³ + 2x − 5.
