------------------------------------------------ Add the two polynomials:

\[(8x^4 + 9x^3 + 10x) + (10x^4 + 3x^3 - 10)\]

Answer :

Final answer:

To add the polynomials (8x⁴ + 9x³ + 10x) and (10x⁴ + 3x³ - 10), you combine like terms resulting in the sum 18x⁴ + 12x³ + 10x - 10.

Explanation:

To add the two polynomials (8x⁴ + 9x³ + 10x) + (10x⁴ + 3x³ - 10), we combine like terms, which means adding coefficients of the terms with the same exponent. We add the coefficients of x⁴ terms, the terms, and the constant terms separately.

The sum of the coefficients of the x⁴ terms: 8 + 10 = 18.

The sum of the coefficients of the terms: 9 + 3 = 12.

Since there are no or x terms in the second polynomial, the 10x term remains unchanged, and we simply add the constant terms: 0 + (-10) = -10.

The final sum of the two polynomials is 18x⁴ + 12x³ + 10x - 10.
