Question

(18x³ - x² + 9x - 3) and (5x³ + 6x² - 14x +11) Add the polynomials (Provide only the coefficients. If a coefficient is negative, include the negative sign on the left side of the number. Do not type 'plus' sign)​

Answer 1

Answer: put it in a caculator

Explanation:

Answer 2

(18x³ - x² + 9x - 3) + (5x³ + 6x² - 14x +11)

Combine 18x^3 and 5x^3.

23x³ - x² + 9x-3 + 6x² - 14x+11

Combine x^2 and 6x^2.

23x³ + 5x² + 9x -3 - 14x + 11

Combine 9x and −14x.

23x³ + 5x² + -5x -3 + 11

Add −3 and 11.

23x³ + 5x² -5x + 8
