Respuesta :
(4x^3 - 2x - 9) + (2x^3 + 5x + 3)
= 4x^3 - 2x - 9 + 2x^3 + 5x + 3
= 6x^3 + 3x - 6 (Answer: C)
= 4x^3 - 2x - 9 + 2x^3 + 5x + 3
= 6x^3 + 3x - 6 (Answer: C)
Answer:
[tex]6x^3+3x -6[/tex]
Step-by-step explanation:
(4x3 − 2x − 9) + (2x3 + 5x + 3)
[tex](4x^3 - 2x - 9) + (2x^3 + 5x + 3)[/tex]
To add two polynomials, we remove the parenthesis
[tex]4x^3 - 2x - 9+2x^3 + 5x + 3[/tex]
To add it , we combine like terms. we add the like terms
[tex]4x^3+2x^3- 2x+ 5x - 9+ 3[/tex]
[tex]6x^3+3x -6[/tex]
